PhotoPGP Full Edition

PhotoPGP creates photos with OpenPGP encryption using the OpenKeychain app

PhotoPGP Full Edition:

o viewer fully supports secure image decryption

o camera and index fully supports public key encryption

o supports private storage directory access - for secure decryption

Your phone's camera stores image files in public shared storage.

This means that when you take a photo, it can be accessed, analyzed, and shared by other apps on your phone.

How can you control this access to your photos? -- by encrypting them before they are written to public shared storage.

PhotoPGP integrates encryption into the process of capturing an image using the OpenPGP framework for Android (OpenKeychain),

and never exposes intermediate image data to public shared storage.

Using your private-key, the PhotoPGP viewer automatically decrypts your photos securely with nothing shared.

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 information

o legal documents (ex. contracts, wills, insurance policies)

o inventory data documenting collections and asset values

o financial and health data (ex. tax records, lab results, receipts)

o proprietary information

PhotoPGP 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.
