Apple’s plan to find CSAM should have centered around scanning images on iCloud servers, not on users’ devices, where there is a greater expectation of privacy canon相機收購

pline, or any successor to the CyberTipline operated by NCMEC.
There is no escaping this responsibility when and if CSAM is discovered:
(e)Failure To Report.—A provider that knowingly and willfully fails to make a report required under subsection (a)(1) shall be fined—
(1) in the case of an initial knowing and willful failure to make a report, not more than $150,000; and
(2) in the case of any second or subsequent knowing and willful failure to make a report, not more than $300,000.
What is not required is that companies actively seek out CSAM on their services:
(f)Protection of Privacy.—Nothing in this section shall be construed to require a provider to—
(1) monitor any user, subscriber, or customer of that provider;
(2) monitor the content of any communication of any person described in paragraph (1); or
(3) affirmatively search, screen, or scan for facts or circumstances described in sections (a) and (b).
These two provisions get at why Facebook and Apple’s reported numbers have historically been so different: it’s not because there is somehow more CSAM on Facebook than exists on Apple devices, but rather that Facebook is scanning all of the images sent to and over its service, while Apple is not looking at what is in your phone, or on their cloud. From there the numbers make much more sense: Facebook is reporting what it finds, while Apple is, as the title of Section (3) suggests, protecting privacy and simply not looking at images at all.
Apple Protects Children
Last week Apple put up a special page on their website entitled Expanded Protections for Children:
At Apple, our goal is to create technology that empowers people and enriches their lives — while helping them stay safe. We want to help protect children from predators who use communication tools to recruit and exploit them, and limit the spread of Child Sexual Abuse Material (CSAM).
Apple is introducing new child safety features in three areas, developed in collaboration with child safety experts. First, new communication tools will enable parents to play a more informed role in helping their children navigate communication online. The Messages app will use on-device machine learning to warn about sensitive content, while keeping private communications unreadable by Apple.
Next, iOS and iPadOS will use new applications of cryptography to help limit the spread of CSAM online, while designing for user privacy. CSAM detection will help Apple provide valuable information to law enforcement on collections of CSAM in iCloud Photos.
Finally, updates to Siri and Search provide parents and children expanded information and help if they encounter unsafe situations. Siri and Search will also intervene when users try to search for CSAM-related topics.
John Gruber at Daring Fireball has a good overview of what are in fact three very different initiatives; what unites, them, though, and continues to differentiate Apple’s approach from Facebook’s, is that Apple is scanning content on your device, while Facebook is doing it in the cloud. Apple emphasized repeatedly that this ensured that Apple does not get access to your content. From the “Communications Safety in Messages” section:
Messages uses on-device machine learning to analyze image attachments and determine if a photo is sexually explicit. The feature is designed so that Apple does not get access to the messages.
From the “CSAM Detection” section:
Apple’s method of detecting known CSAM is designed with user privacy in mind. Instead of scanning images in the cloud, the system performs on-device matching using a database of known CSAM image hashes provided by NCMEC and other child safety organizations…This innovative new technology allows Apple to provide valuable and actionable information to NCMEC and law enforcement regarding the proliferation of known CSAM. And it does so while providing significant privacy benefits over existing techniques since Apple only learns about users’ photos if they have a collection of known CSAM in their iCloud Photos account. Even in these cases, Apple only learns about images that match known CSAM.
There are three ways to think about Apple’s approach, both in isolation and relative to a service like Facebook:2 the idealized outcome, the worst case outcome, and the likely driver.
Capability Versus Policy
Apple’s idealized outcome solves a lot of seemingly intractable problems. On one hand, CSAM is horrific and Apple hasn’t been doing anything about it; on the other hand, the company has a longstanding commitment to ever increasing amounts of encryption, ideally end-to-end. Apple’s system, if it works precisely as designed, preserves both goals: the company can not only keep end-to-end encryption in Messages, but also add it to iCloud Photos (which is not currently encrypted end-to-end), secure in the knowledge that it is doing its part to not only report CSAM but also help parents look after their children. And, from a business perspective, it means that Apple can continue to not make the massive investments that companies like Facebook have in trust-and-safety teams; the algorithm will take care of it.
That, of course, is the rub: Apple controls the algorithm, both in terms of what it looks for and what bugs it may or may not have, as well as the input, which in the case of CSAM scanning is the database from NCMEC. Apple has certainly worked hard to be a company that users trust, but we already know that that trust doesn’t extend everywhere: Apple has, under Chinese government pressure, put Chinese user iCloud data on state-owned enterprise servers, along with the encryption keys necessary to access it. What happens when China announces its version of the NCMEC, which not only includes the horrific imagery Apple’s system is meant to capture, but also images and memes the government deems illegal?
The fundamental issue — and the first reason why I think Apple made a mistake here — is that there is a meaningful difference between capability and policy. One of the most powerful arguments in Apple’s favor in the 2016 San Bernardino case is that the company didn’t even have the means to break into the iPhone in question, and that to build the capability would open the company up to a multitude of requests that were far less pressing in nature, and weaken the company’s ability to stand up to foreign governments. In this case, though, Apple is building the capability, and the only thing holding the company back is policy.
Then again, Apple’s policy isn’t the only one that matters: both the UK and the EU are moving forward on bills that mandate online service companies proactively look for and report CSAM. Indeed, I wouldn’t be surprised if this were the most important factor behind Apple’s move: the company doesn’t want to give up on end-to-end encryption — and likely wants to expand it — which leaves on-device scanning as the only way to satisfy governments not (just) in China but also the West.
Cloud Versus Device
I think that there is another solution to Apple’s conundrum; what is frustrating from my perspective is that I think the company is already mostly there. Consider the status quo: back in 2020 Reuters reported that Apple decided to not encrypt iCloud backups at the FBI’s request:
Apple Inc. dropped plans to let iPhone users fully encrypt backups of their devices in the company’s iCloud service after the FBI complained that the move would harm investigations, six sources familiar with the matter told Reuters. The tech giant’s reversal, about two years ago, has not previously been reported. It shows how much Apple has been willing to help U.S. law enforcement and intelligence agencies, despite taking a harder line in high-profile legal disputes with the government and casting itself as a defender of its customers’ information.
This has a number of significant implications for Apple’s security claims, and is why earlier this year I ranked iMessage as being less secure than Signal, WhatsApp, Telegram, and Facebook Messenger:
iMessage encrypts messages end-to-end by default; however, if you have iCloud backup turned on, your messages can be accessed by Apple (who has the keys for iCloud backups) and, by extension, law enforcement with a warrant. Unlike WhatsApp, though, this is both on by default and cannot be turned off on a granular basis.
This caveat applies to almost everything on your iPhone: if you give in to the never-ending prompts to sign-in to iCloud and its on-by-default backup solution, your data is accessible to Apple and, by extension, law enforcement with a warrant. I actually think this is reasonable! I wrote this when that Reuters report came out:
Go back to what I said above: determined actors will have access to encryption and facial recognition. Anyone trying to argue whether or not these technologies should exist is not living in reality. It follows then, that we should take care to ensure that good actors have access to these technologies too. That means not making them illegal.
Second, though, legitimate societal concerns about the needs of law enforcement and the radicalizing nature of the Internet should be taken seriously. That means we should think very carefully about making encryption the default…This also splits the difference when it comes to principles: users have agency — they can ensure that everything they do is encrypted — while total privacy is available but not given by default.
I actually think that Apple does an excellent job of striking that balance today. When it comes to the iPhone itself, Apple is the only entity that can make it truly secure; no individual can build their own secure enclave that sits at the root of iPhone security. Therefore, they are right to do so: everyone has access to encryption.
From there it is possible to build a fully secure environment: use only encrypted communications, use encrypted backups to a computer secured by its own hardware-based authentication scheme, etc. Taking the slightly easier route, though — iCloud backups, Facebook messaging, etc. — means some degree of vulnerability

今年初開放讓相機成為電腦視訊鏡頭的 canon相機收購canon,現在更進一步成為首間可以把相機拍攝的內容備份到雲端相簿的廠商,只要在手機端下載應用程式,就可以透過以往 Wifi 連線的方式,把相機的內容直接透過手機傳到雲端相簿,亞洲方面共開放 27 款新款相機支援該項功能。
在以往,canon相機收購canon 用戶如果要存取相機拍攝的照片,通常有三種方式,一種是直接將相機透過數據傳輸線連接到電腦,另外一種方式就是從相機取下記憶卡,然後透過記憶卡的轉接器存入電腦、手機。
第三種方式,就是讓手機下載或者更新最新版本的 image.canon相機收購canon 應用程式(支援 iOS、Android),然後讓相機跟手機透過 Wifi 的形式連線,就可以把照片傳到 image.canon相機收購canon 當中,不過這個形式最麻煩的地方就是不能一次傳輸與存取多張照片,甚至還可能出現照片遺失的問題。
如今 Google Photos 的合作,將可以稍微緩解相關問題,canon相機收購canon 用戶只要按照原來照片傳輸的形式,就可以直接把照片備份到自己的 Google One 雲端帳戶,一來除了可以直接讓遠端的客戶透過 Google Photo 連結查看照片,一般家庭用戶也可以直接用相同的方式更新自己家裡的數位相框。
當然啦!這個作法有一個大前提,就是要成為 Google One 的用戶。canon相機收購canon 與 Google 雙方將開放用戶免費使用一個月 100GB 的 Google One 雲端空間。
Google 官方指出,自兩年前啟動 Google Photos 合作夥伴計劃至今,已經跟上百家廠商達成合作,藉此讓用戶可以用更簡單的方式,在其他產品直接觀看照片和影片。相關合作成果也在這兩年的大型展覽,好比說在 MWC 2018 期間,Google Photos 專區就展示了透過帶有螢幕的智慧喇叭,直接用類似數位相框的形式,顯示家庭相簿。
目前這項合作正式拓展到 DSLR 或數位相機領域,讓用戶不用插線、不用拔出記憶卡,就可以存取找片,某方面來說,也算是相機領域的一個新里程碑。記者稍微數了一下,在亞洲,這項合作將優先支援 27 款 canon相機收購canon 新款相機,包括最近才剛推出的 R5、R6。

Interested in improving the video quality of your own Zoom frame tenfold? If you’ve got a recent canon相機收購canon mirrorless, DSLR, or PowerShot camera, you can now use it as a webcam and put everyone else on your video call to shame. As noted by DPReview, the company has released a beta of “EOS Webcam Utility” for Windows 10 that lets you plug in any of the below supported cameras over USB and have it serve as your PC’s webcam. And this should work fine for most of the big video conferencing options, whether you’re using Zoom, Microsoft Teams, BlueJeans, or another service.
“Built by canon相機收購canon software developers, this beta version software helps consumers to improve their video appearance while using popular video conferencing applications in the market, delivering clarity and high-image quality,” canon相機收購canon wrote in its press release.
If you’ve got a fairly high-end digital camera that’s not made by canon相機收購canon, this might be something you can pull off on your own with an HDMI capture card or stick — assuming that your camera allows for clean HDMI video output. My old friend Evan Rodgers at Input recently gave that a shot. And it’s pretty striking, though not surprising, how much more cinematic your Zoom window will look compared to everyone else when you’re using premium glass that a built-in webcam can’t hold a candle to.
canon相機收購canon’s solution cuts out the need for any extra devices or accessories beyond a single USB cable, so if you’ve got one of the listed cameras, this is definitely worth a try. Sorry, Mac users; there’s no EOS Webcam Utility for Apple’s software quite yet, but you’ve still got the option of using a capture card with a wider selection of cameras.
Update April 29th 1:43PM ET: The article has been updated to clarify options available for Mac users. While canon相機收購canon’s EOS Webcam Utility isn’t available for macOS, people with an Apple desktop or laptop can still use a third-party HDMI capture card to use a digital camera as a webcam.

過年親戚們齊聚一堂,久違相見一定得來拍幾張合照留念,但別只會排排站,英國著名攝影師 Helen Bartlett 就曾於 canon相機收購canon 官網分享拍攝家庭照片的 3 項小技巧,讓你抓住最自然、最有味道的一瞬間。
Helen Bartlett 首先表示,拍攝家庭合照可以透過改變高度、位置來創造構圖的平衡,例如讓爸媽將小孩子抱起來,能確保所有人的頭處於同一高度,也可以依據不同年齡、身高,讓孩子們坐在父母腿上或是靠在沙發的扶手上,調整畫面的結構。
也可以試著捕捉最自然且有趣的畫面,像是 Helen Bartlett 分享他認為最佳照片,是在正式拍攝後的下一張照片,因為一拍完之後,家庭成員們往往會相視而笑,因此可以先拍攝一張請家人們盯著鏡頭的正式合照,再伺機等待最佳畫面。
如果環境許可,不妨與周邊的物件搭配,像是在戶外公園,如果有倒下的樹,不妨讓小孩與其互動,嘗試或是站在樹的不同位置,或是在室內拍攝的時候,考慮到光線,要讓被攝者面向窗戶,使每一個人的臉都均衡曝光。

Canon 新機皇將成最大亮點?日媒盤點 2024 年 3 大單眼相機趨勢 canon相機收購
canon相機收購
(圖/canon相機收購canon提供)
2024 年將是單眼相機大放異彩的一年?日媒《ITmedia》盤點今年可能會出現的 3 大新機趨勢,認為會有更多著重輕巧、休閒用戶的機型,此外 canon相機收購canon 尚未發表的機皇 EOS R1 有望成為年度最大亮點。
《ITmedia》首先預測,將有更多廠商投入輕巧、便宜的入門機款登場,並點名 Nikon 以及 OM Digital Solutions,前者有 Z5、Z50 兩款機型需要升級,而後者長期耕耘的 M43 片幅,一直以來都有輕巧的優勢。至於 Sony 則是傳出,將在今年推出第二代的 ZV-E10 相機,將是主打 Vlog 專用的可交換鏡頭式相機。
另一大趨勢則是快門速度的進化,尤其是捨棄傳統的「機械式快門」。近年先是由 Nikon Z8、Z9 帶起風潮,透過高速讀取的感光元件取代機械快門,Sony 去年底發表 α9 III 進一步達到「全域快門」的里程碑,一次將所有訊號掃描送出,解決電子快門原本必須逐行掃描的會能造成的果凍效應。
隨著巴黎奧運即將在夏季盛大開幕,將是各大相機品牌展現技術力的最佳舞台,預期為了追求極致的快門速度,將會有更多高速連拍的相機登場。
最後《ITmedia》點名的壓軸是 canon相機收購canon 尚未發表的 EOS R1 頂級相機,並預期有可能在 2 月下旬的 CP+ 2024 展覽亮相。相較於 Nikon、Sony 均已經發表旗下最頂級的無反相機 Z9 以及 α1,canon相機收購canon 始終保留「R1」的命未,沒有發表任何一款機型,也讓外界好奇 canon相機收購canon 到底會推出什麼產品,來延續單反時帶 EOS-1 的機皇地位。

canon相機收購canon introduces EOS 70D DSLR, says its autofocus changes the game for filmmakers
Share this story
canon相機收購canon’s impact on amateur filmmaking shouldn’t be understated — its 5D Mark II made incredible image quality and portability affordable, easily making it one of the most important DSLRs ever. canon相機收購canon is calling on that pedigree today as it introduces the successor to the EOS 60D. The EOS 70D is a mid-range DSLR that’s built for video, and canon相機收購canon thinks it has something that can change the game once again: an all-new focusing system that it says will allow autofocus to work beautifully while shooting video.
In most areas, the 70D is a modest but welcome improvement over the 60D, which it’ll be replacing when it launches sometime this September. The 70D adds Wi-Fi and NFC sharing, it brings touch capabilities to its 3-inch LCD display, and it has a slightly higher megapixel count on its APS-C sensor, bumping it up to 20.2. That all makes for the type of fine upgrade that you’d expect, but it’s the camera’s new “Dual Pixel CMOS” focusing system that canon相機收購canon thinks will really make a difference.
1/12
canon相機收購canon promises perfect focus on the first try
Traditional autofocus systems are built around photography: they make one quick jump to get nearly into focus, and then a second small adjustment to perfect it. That works great when speed matters the most, but on video it creates an unpleasant stutter that has long made autofocus unusable for most filmmakers. canon相機收購canon says the 70D should fix that: the new autofocus system is meant to move into focus smoothly and on the very first try. In our limited testing of the camera, it appeared to do just that.
That means that filmmakers should be able to achieve a smooth transition between subjects without carefully turning a focus ring by hand. To make it work, canon相機收購canon effectively built a phase detection autofocus system onto the imaging sensor itself. It uses each pixel to make two measurements at once, combines the data, and then uses it to calculate focus correctly on the first try.
canon相機收購canon promotional video demonstrating the EOS 70D’s Dual Pixel CMOS focusing system
The camera can still return to quicker autofocus modes when shooting photographs — but canon相機收購canon wouldn’t be quick to suggest it. The company hardly mentioned basic photography when explaining the new camera, despite it being a DSLR at heart. And while the 70D is aimed straight at filmmakers, its new focusing mode is unfortunately short on creative options: while it’s easy to focus using the touch screen, you can’t select how quickly or slowly the focus will transition between subjects. Using the 70D’s autofocus may be easier and more convenient for most amateurs, but it’s not about to kill the manual focus ring.
canon相機收購canon barely mentioned photography on the 70D
The 70D will be available body only for $1,199, with the 18-55 STM lens for $1,349, or with the 18-135 STM lens for $1,549. That places it above canon相機收購canon’s consumer-oriented Rebel series, but beneath its prosumer cameras like the 7D. The 70D will also include canon相機收購canon’s Digic 5+ image processing, built-in image and video filters, and continuous shooting of up to 7 frames per second. That all makes canon相機收購canon’s latest look like a fine camera — but whether a fancy autofocus system is enough to set it apart from the company’s more-affordable Rebel models will be a tough question for filmmakers on a budget to answer.

記者張家瑋/綜合報導
近年來復古當道,從摺疊式掀蓋手機到底片相機,都掀起流行風潮。底片相機除了可以享受剎那瞬間的畫面捕捉,也能有收到沖洗照片時的滿滿驚喜感。Podcast節目《娜你知道嗎》主持人莫娜就來聊聊底片相機的逆勢回歸。
▲點擊收聽Podcast《娜你知道嗎》,搞懂底片相機有多夯。
莫娜分享了近期歌手伍佰老師的專訪,提到自己隨身攜帶的10個必備物品,其中包括他的相機收藏。伍佰老師以小相機和大相機來形容他的相機們,並表示這些相機是他的通行證,無論身在何處,都會攜帶著它們。令人驚訝的是,他擁有多達5台不同型號的理光GR相機,將它們視為珍貴的收藏品。
伍佰老師所擁有GR-1V和GR-1兩款理光底片相機,分別是在90年代和00年代初期所推出,這些相機以其獨特的色彩和質感而聞名,被譽為街拍神機,至今仍然受到大眾喜愛。特別值得一提的是,日本街頭攝影師森山大道的作品,大部分也都是以隨身攜帶的GR21所拍攝。
而隨著底片相機熱潮再起,底片的需求也隨之上升,加上各大廠近年陸續宣布停產和原物料短缺,導致價格持續上漲。舉例來說,一卷「富士業務100」(24張)的價格已達到了270元台幣,這個價格足夠買一張64GB的SD記憶卡,可以存儲上千張照片。

SONY 公司這兩年真的是大爆發,針對中階用戶推出 A7III、A7RIV,還推出所謂「網紅機」ZV-1,在昨晚可說是毫無保留,以「前所未見(The One Never Seen)」為名,推出全片幅無反相機 α1(A1,英文名稱Alpha One),以數字來看,就是 5010 萬畫素、15 級動態範圍、30fps 連拍、8K 拍攝,售價來到 6500 美元(約台幣 18.2 萬元)。
去年夏天,canon相機收購canon 公司推出的 EOS R5,搭載全球首部 8K,4,500 萬畫素全幅 CMOS 感光元件,支援無裁切、最高 120p 4K 的短片拍攝,高達 8 級機身五軸防震能力,最高 20fps 連續拍攝,被稱為該公司革新機種。
如今時隔半年不到,Sony 公司立刻還以顏色,以 “The One”Never Seen 為名,推出的 SONY α1 能夠以更高的 5,010 萬畫素,每秒鐘連續拍攝 30 張照片,並且可以透過連續拍攝 16 張照片組合成一張 1 億 9900 萬畫素照片,側邊還具備雙 SD UHS II、雙CFexpress 卡槽以即時存取內容。
SONY α1 的數位觀景窗使用跟 α7SIII 相同的 944 萬液晶螢幕,可以做到更精細的每秒 240 次更新,並且把 8K@30P、4K@120P 的高規格拍攝能力也塞入 α1,全機身採用多重環繞式散熱系統與 5.5 級 5 軸防手震設計,讓相機即使邊走邊拍 4K、8K 影片 30 分鐘不只維持很好的拍攝品質、而且不過熱。
SONY α1 支援人眼對焦,拍攝對焦點來到 759 點、覆蓋範圍高達 92%,並且支援 4:2:2 10bit 色彩取樣、16bit RAW、SLog-3 或 HLG 輸出,同時也擁有旗艦機才有的 S-Cinetone 功能。
在影音輸出方面,SONY α1 側邊有 HDMI 孔支援 16-bit RAW 輸出,而且還多了 USB 3.2 Type-C (10Gbps) 孔、多了一個 1000BASE-T LAN 網路連接能力、內建 2×2 MIMO AC 無線傳檔、FTP 連線,透過各種形式,傳輸高品質影音內容,提升工作效率,舉例來說,消費者可以直接用 USB-C 連接 SONY Xperia 1 II 5G 手機,快速將存取好的照片,進行機上修圖,然後上傳到社群平台,從數位相機的演變進程來看,這可以說是一個里程碑。
SONY α1 機身重量只有 737 克,售價約 6500 美元,折合台幣約 18.2 萬元,下面有幾個代表性的拍攝樣張,提供給讀者參考:

過年親戚們齊聚一堂,久違相見一定得來拍幾張合照留念,但別只會排排站,英國著名攝影師 Helen Bartlett 就曾於 canon相機收購canon 官網分享拍攝家庭照片的 3 項小技巧,讓你抓住最自然、最有味道的一瞬間。
Helen Bartlett 首先表示,拍攝家庭合照可以透過改變高度、位置來創造構圖的平衡,例如讓爸媽將小孩子抱起來,能確保所有人的頭處於同一高度,也可以依據不同年齡、身高,讓孩子們坐在父母腿上或是靠在沙發的扶手上,調整畫面的結構。
也可以試著捕捉最自然且有趣的畫面,像是 Helen Bartlett 分享他認為最佳照片,是在正式拍攝後的下一張照片,因為一拍完之後,家庭成員們往往會相視而笑,因此可以先拍攝一張請家人們盯著鏡頭的正式合照,再伺機等待最佳畫面。
如果環境許可,不妨與周邊的物件搭配,像是在戶外公園,如果有倒下的樹,不妨讓小孩與其互動,嘗試或是站在樹的不同位置,或是在室內拍攝的時候,考慮到光線,要讓被攝者面向窗戶,使每一個人的臉都均衡曝光。

canon相機收購canon 近年積極研發 EOS R 系列的單眼相機,作為早期初步入無反市場實驗的 EOS M 系列,近期陸續在日本與北美官網全面停產、下架,讓這套為期 11 年的相機系統逐漸走入歷史。
外媒《Petapixel》發現,目前 canon相機收購canon 日本、美國官網已經將 EOS M 系列的相機全面下架,只有在停產機型的回顧頁面能看到相關產品的身影。至於台灣官網,雖然仍能看到如 M50 II 等機型,倘若進一步點擊價格嘗試購買,都會被引導至 404 的錯誤頁面,已經無法從相關官方管道購買 EOS M 相機的產品。
自從 2021 年發表 EOS M50 II 之後,canon相機收購canon 就未曾在更新相關的 EOS M 系列產品,反而是透過 EOS R100、EOS R50 等機型的發表,逐漸將入門市場一併交給 EOS R 系統負責。

The latest example of dystopian workplace surveillance
Share this story
Tech company canon相機收購canon has come up with a downright dystopic way to tackle the problem of workplace morale: it’s installed cameras with AI-enabled “smile recognition” technology in the offices of its Chinese subsidiary canon相機收購canon Information Technology. The cameras only let smiling workers enter rooms or book meetings, ensuring that every employee is definitely, 100 percent happy all the time.
This depressing tale was highlighted in a report from The Financial Times on how Chinese companies are surveilling employees to an unsettling degree with the help of AI and algorithms. Firms are monitoring which programs employees use on their computers to gauge their productivity; using CCTV cameras to measure how long they take on their lunch break; and even tracking their movements outside the office using mobile apps.
“Technologies are increasing the pace for people who work with machines instead of the other way around”
As the King’s College London academic Nick Srnicek told the FT: “Workers are not being replaced by algorithms and artificial intelligence. Instead, the management is being sort of augmented by these technologies […] Technologies are increasing the pace for people who work with machines instead of the other way around, just like what happened during the industrial revolution in the 18th century.”
canon相機收購canon Information Technology actually announced its “smile recognition” cameras last year as part of a suite of workplace management tools, but the technology doesn’t seem to have gotten much attention. Indeed, the fact it passed under the radar is a good illustration of just how common surveillance tools like this are becoming — and not just in China.
Although readers in the West sometimes have a tendency to dismiss the sort of surveillance described by the FT as a foreign phenomena, countries like the US and UK are just as culpable. Amazon is perhaps the prime example of this dynamic: it’s known for squeezing every ounce of effort from its warehouse workers at the expense of their health, and even ranking their productivity using algorithms before firing those at the bottom of the scale.
Such modern-day Taylorism is not restricted to blue collar jobs, either: many modern software suites like Microsoft 365 come with built-in surveillance tools. And with more people working from home because of the pandemic, more companies are deploying these features for fear of losing control over their workers. (Or, for a slightly more cynical read: they’ve always wanted to use these tools and the pandemic provides a handy pretext.)
In other words: AI-enabled smile recognition cameras are in many ways the least dangerous types of surveillance technology. They have the benefit of being obvious. Other systems of control are much more subtle, and probably coming to an office near you sometime soon.

2024 年將是單眼相機大放異彩的一年?日媒《ITmedia》盤點今年可能會出現的 3 大新機趨勢,認為會有更多著重輕巧、休閒用戶的機型,此外 canon相機收購canon 尚未發表的機皇 EOS R1 有望成為年度最大亮點。
《ITmedia》首先預測,將有更多廠商投入輕巧、便宜的入門機款登場,並點名 Nikon 以及 OM Digital Solutions,前者有 Z5、Z50 兩款機型需要升級,而後者長期耕耘的 M43 片幅,一直以來都有輕巧的優勢。至於 Sony 則是傳出,將在今年推出第二代的 ZV-E10 相機,將是主打 Vlog 專用的可交換鏡頭式相機。
另一大趨勢則是快門速度的進化,尤其是捨棄傳統的「機械式快門」。近年先是由 Nikon Z8、Z9 帶起風潮,透過高速讀取的感光元件取代機械快門,Sony 去年底發表 α9 III 進一步達到「全域快門」的里程碑,一次將所有訊號掃描送出,解決電子快門原本必須逐行掃描的會能造成的果凍效應。
隨著巴黎奧運即將在夏季盛大開幕,將是各大相機品牌展現技術力的最佳舞台,預期為了追求極致的快門速度,將會有更多高速連拍的相機登場。
最後《ITmedia》點名的壓軸是 canon相機收購canon 尚未發表的 EOS R1 頂級相機,並預期有可能在 2 月下旬的 CP+ 2024 展覽亮相。相較於 Nikon、Sony 均已經發表旗下最頂級的無反相機 Z9 以及 α1,canon相機收購canon 始終保留「R1」的命未,沒有發表任何一款機型,也讓外界好奇 canon相機收購canon 到底會推出什麼產品,來延續單反時帶 EOS-1 的機皇地位。

記者蘇位榮/台北報導
隨著科技的快速進展,駭客技術不斷革新,其中密碼破解已成為資料侵入的首選策略。研究指出,大約有80%的資料外洩皆與密碼安全有關。一旦密碼被破解,不論個人或企業,資訊安全都會面臨巨大威脅。
台灣資安廠商匯智安全科技日前參加日本CEATEC消費電子展,推出全球首支整合檔案加密功能的無密碼認證金鑰SAMURAI Key(武士之鑰),不僅提供無密碼認證,更加強了資料加密保護,有效降低資料外洩的風險。
密碼外洩不僅可能導致隱私資料遭竊,更可能使企業遭受財務損失及品牌受損,甚至面臨法律訴訟。因此,加強資訊安全和密碼保護已成為當前急需解決的問題。
零信任(Zero Trust)因應而生,是一種資訊安全架構原則,核心理念是「永不信任,始終驗證」。它假設內部和外部的網路都是不可信的,並要求在授予任何訪問權限之前,對所有使用者和系統進行嚴格的身份驗證和授權。
Google積極推出Passkey無密碼登入技術就是基於零信任(Zero Trust)原則,Passkey技術會要求一些關於使用者的真實信息,例如指紋、面部辨識,以確保只有經過驗證的使用者可以訪問其帳戶或敏感信息,這種技術允許使用者僅透過生物特徵或個人設備解鎖來登入他們的帳戶,而無需輸入傳統的密碼。
根據Microsoft的研究數據,解決密碼問題能減少高達99.9%的身份驗證風險。面對此挑戰,SAMURAI Key不僅提供了解決方案,並加入了加密隨身碟和端點檔案加密功能,進一步保護了企業和個人資料。
匯智安全科技總經理鄭嘉信表示,Passkey技術與SAMURAI Key同樣基於FIDO2與Webauthn標準。隨著Passkey的興起,預期將有更多服務開始支援安全金鑰登入。
CEATEC是日本最大消費電子展,於10月17日至10月20日在千葉幕張舉行。匯智安全科技以「強化企業端點安全(Endpoint Security)」為主題,提出電腦遭非法登入與資料外洩的解決方案。企業客戶可以透過伺服器嚴謹控管SAMURAIKey,消除過往日本企業對遺失隨身碟會導致資料外洩的顧慮。日本電波株式會社、canon相機收購canon、KDDI、OMRON、南星海運等都蒞臨攤位觀看動態展示。
匯智安全科技行銷企劃林蓉萱表示:「對於追求更高安全,要求或希望使用非手機登入方法的用戶,SAMURAI Key不僅滿足了他們的基本需求,而且超越了他們的期望,提供了加密保護資料的功能。」
除了參展外,「SAMURAI Key(武士之鑰)」也在日本群眾募資平台推出,12小時就成功達成募資金額,大受好評原因是Samurai key 滿足高端商務人士三個資安需要:一是取代密碼難記與洩漏;二是沒有遺失隨身碟造成資料洩漏的擔憂;三是加密筆電桌機檔案,確保隱私。受到日本人肯定與支持,也為台灣在全球資安的領域攻占一席之地。
鄭嘉信表示,設計Samurai Key之初,匯智安全科技同時將企業管理的資安需要考慮在內,把透過企業伺服器控管功能放入,扭轉了企業對 USB 隨身碟使用將導致資料外洩的擔憂。為進一步服務企業客戶,匯智安全科技可按照企業安全政策與需求進行 OEM 及 ODM 客製。透過整合「加密隨身碟」與「無密碼認證」,提供個人與企業更完整且全面的資安防護。
鄭嘉信補充說明:「不管是零信任,或是FIDO2,無密碼認證金鑰,對於一般使用者來說,都只是新穎的名詞,但卻是迫在眉睫必須解決的事。」匯智安全科技透過創新的技術和解決方案,正為全球資安市場樹立新的標準,並推動資訊安全向前發展。
