E-Signatures provides data storage and access functions for electronic records. It is used in conjunction with E-Notebook as a long-term storage system. While E-Notebook is intended to capture and record data as the experiments are carried out, E-Signatures serves as the repository for finished experiments and other documents. Electronic records must be available indefinitely, and their authenticity must be verifiable independently of the E-Notebook system. In addition to the record, E-Signatures’ long-term archive includes a digital signature, a timestamp, and associated metadata. Managers, patent attorneys, and scientists can retrieve records based on searches over the metadata.
