Fa un parell de setmanes, es va descobrir que l'iPhone enregistrava imatges de tot el que feia l'usuari (L'iPhone enregistra tot el que fa l'usuari). Ara la mateixa persona que va fer el descobriment ha trobat un mètode per evitar que el telèfon faci això: Hacker Resolves iPhone Screenshot Security Issue
Granted, fixing the problem requires hacking — or "Jailbreaking," as the community calls it — your iPhone yourself. (Steps on that procedure can be found at the iPhone DevTeam blog.) And as you might imagine, tampering with that effect will make things less pretty: When resuming an application, you'll get the default screen, since you'll no longer have stored screenshots cached. For example, when re-launching your Mail application it will always zoom to the front and appear as though it's empty, but after the application fully resumes it'll look normal, Zdziarski explained.
Nonetheless, if privacy is your utmost concern, here are the steps:
1. After Jailbreaking your iPhone, use an OpenSSH application to gain root privileges to your iPhone.
2. Using the OpenSSH app, enter the following commands in the prompt:
- # rm –rf /var/mobile/Library/Caches/Snapshots
- # ln –s /dev/null /var/mobile/Library/Caches/Snapshots
Those commands will disable screenshot writing. And if you wish to undo this, delete the symlink and the directory will get recreated.
