Practical applications of homomorphic encryption algorithms?

邮差的信 提交于 2019-12-20 08:04:25
问题 It appears there there were interesting things going on in cryptography: the first homomorphic encryption scheme appeared recently (explanation, HT). Roughly speaking, it is a way of encoding x into f(x) such that you can compute f(x+y) easily knowing f(x) and f(y) even though you can't easily restore x and y (and same for f(x*y) ). What are practical applications for schemes of this type (once their security has been established)? To me, it appears they could make writing algorithms for

Getting the privacy setting of a status message?

£可爱£侵袭症+ 提交于 2019-12-20 05:22:08
问题 Does anyone know if it's possible to query the privacy settings for status updates? I know you can get them for photo albums, but for my application it would be useful to be able to pull up a random status message from a while back and say "You shared this post with everyone, would you still do this today?" to see how people's attitudes to sharing online change. I'm not after anything fancy, just "friends", "public" or "custom" would be great. Cheers 回答1: If it's a user's own status updates

问题 (Related to Is there a secure Browser Cache? ): Do any of the implementations of HTML5 session storage write to disk ever? e.g. can I rely on having a "secure"/"private" cache that I know will not be able to persist beyond the browser session whether it times out is ended/logs out browser closes/crashes/power button on computer See HTML5 Browser Application Cache HTML5 sessionStorage 回答1: Safari uses SQLite, and probably other will follow suite with that solution. As for the standard it says:

☆樱花仙子☆ 提交于 2019-12-17 20:26:45
问题 In my iOS app I am accessing the user's photo gallery. The first time the user does this, it asks them for permission.

问题 I tried to make my AppProject iOS 8 ready. I had read a lot about [_locationManager requestWhenInUseAuthorization]; and the entry in plist NSLocationWhenInUseUsageDescription So I changed all the necessary code lines. It works fine, but now I have copied my project again from my iOS 7 base to include new features. But when I make the changes for the iOS8 Location Privacy the Popup doesn't appear anymore. My code worked until I copied. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist

问题 I want to hide some products from a group of users. I set up the groups and products in the editproducts.cgi configuration.

Way to use Fusion Tables with the Google Maps API while maintaining privacy?

杀马特。学长 韩版系。学妹 提交于 2019-12-13 05:09:43
问题 It's my understanding that the only way to use a private Fusion Table with the Maps API is if you're using the Business version of the API. Only public and unlisted tables can be used normally. I would really like to realize the performance benefits of Fusion Tables but am not interested in paying for a business license. My question is this: How secure could an unlisted table be? The data I'll be displaying is sensitive, but not critical. It is unlikely to be sought out specifically, or

Set Default Activity Privacy to public on app install

一个人想着一个人 提交于 2019-12-13 05:03:21
问题 I've noticed in my last app that it installs with the Activity Privacy set to "Only me" and when the new permissions dialog shows there's no way to change the privacy from there, and this app installs with "Only me" privacy. I wanted to force the Public value for this app privacy and I don't know how to do it. I show the permissions dialog using PHP: $params = array( 'scope' => 'email', 'redirect_uri' => 'https://mytabpage' ); $loginUrl = $facebook->getLoginUrl($params); 回答1: The solution can
