Validating one or more data blocks in a computer-implemented document derived from another computer-implemented document |
摘要 |
In one embodiment, a system for validating one or more data blocks in a document derived from another document includes one or more processors collectively operable to (1) access a number of first values in a predetermined portion of a source document; (2) apply a code-generating algorithm to the first values to generate a first code representing the first values; (3) access a number of second values in a predetermined portion of a document derived from the source document, the predetermined portion of the derived document corresponding to the predetermined portion of the source document; (4) apply the code-generating algorithm to the second values to generate a second code representing the second values. If the first code matches the second code, it can be assumed that within a predefined probability the derived document was accurately derived from the source document in that the second values match the first values.
