ABSTRACT:
An improved method of storing or retrieving electronic records. An image identification code and time data provided by a trusted source, as well as a password, are combined to generate a key. The image identification code and time data are stored in a public directory associated with the image data stream. Further, attributes of the image stream, such as its size and a hash of at least a segment of the image data, are determined. The attributes are then used to generated a verification code. The verification code is placed in a private area associated with the data image stream, and the private area is encrypted with the previously generated key.
