    摘要: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for efficiently storing information. For example, lower-quality copies of files can be stored locally, and higher-quality, original versions of files can be stored on the Internet. Storing a lower-quality or lower-resolution version of a file locally can reduce local storage requirements. The higher-quality, or higher resolution, original version of a file can be retrieved from the cloud if the locally stored version is not of sufficient quality for a particular use. However, the lower-quality copy may be of sufficient quality for most usages.

    摘要: Electronic signature functions, such as electronically signing an electronic record, verification of an electronic signature and issuance of keys, may be performed by a server or other central computer. For electronic signing, the server may access a key on a protected database and encryption programs to electronically sign an electronic record. For signature verification, the server may receive the electronic record and electronic signature, determine a key to decrypt the electronic signature, and then determine whether the electronic signature is valid. For issuance of keys, the server may receive a user request to generate keys, may generate the keys, and store the keys in a database which is accessible by the server, but which may not be accessible by the user.
