And you can allow others access to specific photos by selecting their PGP public-keys when encrypting.PhotoPGP is used to take photos of sensitive, private, or confidential information such as health, financial, and personal identity records.o private hand-written notes (ex. password sheets)o personal identity informationo legal documents (ex. contracts, wills, insurance policies)o inventory data documenting collections and asset valueso financial and health data (ex. tax records, lab results, receipts)o proprietary informationPhotoPGP enables you to store your encrypted images safely anywhere (email, thumb-drive, cloud and off-site backup services) preventing tampering and unauthorized access.PhotoPGP keeps your private data private, and shares only what you want -- in confidence.Visit photopgp.com for more information.PREREQUISITESo install OpenKeychain, an implementation of OpenPGP for Android.
