Abstract: The present disclosure involves systems and computer implemented methods for protecting portions of electronic documents. An example method includes receiving a request for access to an electronic file having sections, at least one section encrypted using a first key based on a first password. A second key is generated in response to receiving a second password, wherein the second key is generated based on the second password. The second key is compared to the first key. If the second key is identical to the first key, the least one section of the electronic file encrypted using the first key is decrypted using the second key. The electronic file is then presented such that the section(s) previously encrypted using the first cryptographic key is made visible. If the second key is not identical to the first, the electronic file is presented with the encrypted section(s) obscured.

Abstract: Systems and methods for the semantic compression of structured data include identifying attributes of elements in a collection structure, such as a table. The attributes may be grouped and the grouping used to consolidate attribute values used in the elements. An index of repeated attribute values may also be generated and used to replace the attribute values in elements of the structured data.
