Abstract:
1. A method for securely providing privately viewable data in a publicly viewable display comprising the steps of: generating an encryption key pair comprising a public key and a private key; encrypting a syncstream mask using said public key; forwarding said encrypted syncstream mask to a pair of active glasses; decrypting said encrypted syncstream mask with said private key; displaying private data frames interspersed among public data frames according to a sequencing pattern; encoding a syncstream based upon said syncstream mask, said syncstream specifying when to activate shutters in said active glasses in synchronization with said sequencing pattern; and, applying said decrypted syncstream mask to said encoded syncstream to determine when to activate said shutters in said active glasses, wherein said sequencing pattern is encoded through a use of the syncstream mask to preserve a confidentiality of the sequencing pattern.
