JSTOR/Havard Object Validation Environment (JHOVE) is software used for format identification, validation, and characterization of digital images during post scanning tasks.Whereas the validation process establishes the level of compliance of the digital image to the specifications of its purported formats. It checks the well-formedness, validity, and consistency of digital objects. Format characterization determines the salient features of a given object. JHOVE uses standards established by Open Archival Information System (OAIS) reference model ISO/IEC 14721 to report information such as digital image file path/URL, last modification date, byte size, format, format version, MIME types./span>

The JHOVE tool supports routine identification, validation and characterization of digital images stored in digital repositories.
