External links modified[edit]

Hello fellow Wikipedians,

I have just added archive links to one external link on Canvas fingerprinting. Please take a moment to review my edit. You may add {{cbignore}} after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

Citing ad blocking add-ons[edit]

About the revert of my edits (831830099, 831830216) made by Silver hr, I disagree with the motivation he brought: This specific information informs readers of various options to defend against canvas fingerprinting. (831831699).

In fact, giving the user possibility to see more than those three options (there are definitely more, one of all uBlock Origin) it is more useful than limiting the possibilities for them.

Obviously, listing all add-ons that support that functionality is infeasible, a burden for maintenance, and non relevant to the entry. Hence, I consider more useful to redirect the user to the whole ad blocking category, maybe better structuring it with a clearer list with supported features (ie: do not limit one entry meaningfulness because another one isn't so well-structured).

Hoping for a useful discussion --Stud94 (talk) 12:41, 22 March 2018 (UTC)[reply]

I was the one who reverted your edit. As far as I know, not all ad blockers block canvas fingerprinting. Why don't we simply list the major ad-ons that block canvas fingerprinting. I think we should only add the ones that are verifiable in reliable sources. Although it may be a bit of a maintenance issue, I think it's better that leaving our readers in the dark.- Mr X 🖋 13:36, 22 March 2018 (UTC)[reply]

Ok, maybe for users is better that way... I think I can take some time to check some of them and, if it is possible, I'll cite something that confirms their support, also. --Stud94 (talk) 14:07, 22 March 2018 (UTC)[reply]

OK, sounds good. Thanks. - Mr X 🖋 19:07, 22 March 2018 (UTC)[reply]

Proposed merger with Device fingerprint[edit]

Is There a "Legitimate" Purpose for "Canvas Fingerprinting"? If so, the Article should Mention it.[edit]

As I read the Article, it seems the whole purpose of "Canvas Fingerprinting" is to identify the computer browsing the Server, which seems counter-intuitive to me, as I've read somewhere that this information is used by websites to help render the web pages in the best way possible. At least that's my understanding. The Article should address the information from this perspective, and clearly spell out what (if any) legitimate reasons there may be, and then balance those off against privacy/security concerns. As it stands, the Article seems aimed only at the "surveillance" aspect. At least that's how it appears to me.2605:6000:6947:AB00:75A9:D270:2421:59E (talk) 06:58, 1 October 2018 (UTC)[reply]

2605:6000:6947:AB00:75A9:D270:2421:59E That's probably because (and don't quote me on this) the majority of the "visible" cases of canvas fingerprinting are the uses by trackers and ad networks. It is a technique that can be used to get useful information about the client, and if leveraged fully, it can provide a unique fingerprint of the useragent, which can be used to uniquely identify a visitor to your site (or sites), even if the visitor never voluntarily provided any identifying information to you. It is a tool, and like any tool it can be used for good or bad purposes. There isn't much coverage of the positive uses of canvas fingerprinting because most sites that need that level of identification would usually be providing services that would require the user to log in anyway. Someone who wanted to identify users when they don't want to be identified (or when they have a reasonable expectation of anonymity) is usually not operating in the user's best interests. If you can find notable examples of sites that use canvas fingerprinting for legitimate purposes, you are welcome to add it to the article, with a reliable source. — AfroThundr ^{(u · t · c)} 01:26, 2 October 2018 (UTC)[reply]

Proposed merger with Browser fingerprint[edit]

FYI

– Discussion taking place at Talk:Device fingerprint § Overlap with Browser fingerprint and Canvas fingerprinting

My mistake not to place this template sooner. Didn't realize I could/should until I got reverted :) The content and works cited of this page seem (in my opinion) to be a neat subset of what is contained in browser fingerprint, and I think readers would be better served by having all browser fingerprinting techniques consolidated. Happy to see that people are noticing the changes made to this page. Let's continue the discussion on the other talk page? Aeffenberger (talk) 04:58, 31 January 2020 (UTC)[reply]
