Abstract
Provided are methods and a validation system that includes a signature device and a verification device for verifying a content. The signature device may generate verification information for each segment of a divided content and may generate signature information to verify the integrity of each segment and whether a corresponding segment is a part of a content. When a segment is received, the verification device may verify integrity of the segment and whether the segment is a part of the content, based on the verification information and the signature value received from the signature device.
