Secure information distribution system utilizing information segment scrambling

A method for recovering an information stream having a first segment sequence from an encrypted re-sequenced information stream having a second segment sequence, said method comprising the steps of:

• recovering an index relating said second segment sequence to said first segment sequence;
• decrypting said encrypted information segments to form respective decrypted information segments;
• re-sequencing, using said recovered index, said decrypted information segments to form an information stream comprising a plurality of image segments arranged according to said first segment sequence;
• and
• decompressing after said re-sequencing step a plurality of image frames forming each of said information stream segments by employing prediction-based decompression.

An apparatus comprising:

• a segmentation module, for segmenting an information stream into a plurality of information stream segments, said information stream segments arranged according to a first segment sequence, each of said information stream segments comprising a plurality of image frames;
• a compression module, for compressing said image frames after said segmenting step by employing prediction-based compression;
• a re-sequencing module, for re-arranging according to a second segment sequence, said information stream segments including said compressed image frames, said first segment sequence being related to said second segment sequence by an index;
• and
• an encryption module, for encrypting said re-sequenced information stream segments and said index.
