Abstract

Invention allows users to view security camera footage, whilst allowing personal data (i.e. image of person) to remain concealed from viewer. Video storage, comprising: segmentation of received video data frames into foreground 214 and background 215 data; separate encryption (Fig. 1; 104) of foreground and background data from each other; storing (Fig. 1; 106) encrypted foreground and background data separately. Segmentation may involve obtaining a reference frame (i.e. background of previous video frame), which is then subtracted from each frame of video. The reference frame may be updated periodically to account for changes in illumination (i.e. due to daylight). Encryption keys may be stored in second storage module (Fig. 1; 108). The system may comprise verification module (Fig. 4; 410) for calculating unique verification markers, which may comprise a hash, for each of foreground and background data. The system may comprise access module with three different levels of encryption access: first 612A shows encrypted foreground 613 and encrypted background 614 data; second 612B shows decrypted background data 616 and encrypted foreground data 613; third 612C shows decrypted foreground data 615 and decrypted background data 616. The system may allow for verification of the third clearance level to determine image tampering.
