Abstract
Provided are methods and apparatuses for providing and using content allowing integrity verification for determining whether the content has been altered. In the method of providing content allowing integrity verification, the content is divided into a plurality of parts, and integrity verification information for each of the plurality of parts is inserted into the content. Accordingly, it is possible to verify the integrity of the content transmitted even if the whole content file is not received and stored.
Claims44
A method of providing content allowing integrity verification, the method comprising:
- dividing the content into a plurality of parts;
- and
- inserting integrity verification information for each of the plurality of parts of the content into the content.
A method of using content allowing integrity verification, the method comprising:
- receiving the content containing integrity verification information for each of a plurality of parts of the content;
- and
- verifying integrity of each of the plurality of parts based on the integrity verification information.
An apparatus for providing content allowing integrity verification, the apparatus comprising:
- an integrity verification information providing unit which divides the content into a plurality of parts and inserts integrity verification information for each of the plurality of parts into the content.
An apparatus for using content allowing integrity verification, the apparatus comprising:
- a content receiving unit which receives the content containing integrity verification information for each of a plurality of parts of the content;
- a decoder which decodes the received content and detects the integrity verification information;
- and
- an integrity verification unit which verifies integrity of each of the plurality of parts based on the detected integrity verification information.
A computer readable medium having recorded thereon a computer program for executing a method of providing content allowing integrity verification, the method comprising:
- dividing the content into a plurality of parts;
- and
- inserting integrity verification information for each of the plurality of parts of the content into the content.
A computer readable medium having recorded thereon a computer program for executing the method of using content allowing integrity verification, the method comprising:
- receiving the content containing integrity verification information for each of a plurality of parts of the content;
