Abstract: The present invention relates to a composition comprising an amino acid-modified polymer, a carboxypolysaccharide, and may further include a metal ion for anti-adhesion and vector application. More specifically, the invention relates to a thermosensitive composition having enhanced mechanical and improved water-erosion resistant properties for efficiently preventing tissue adhesions and can serve as a vector with bio-compatible, bio-degradable/absorbable, and in-vivo sustainable properties.

Abstract: Synthetic amino acid-modified polymers and methods of making the same and using the same are disclosed. The synthetic amino acid-modified polymers possess distinct thermosensitive, improved water-erosion resistant, and enhanced mechanical properties, and are suitable of reducing or preventing formation of postoperative tissue adhesions. Additionally, the amino acid-modified polymers can also be used as a vector to deliver pharmaceutically active agents.

Abstract: A data verification system comprises a provider-end computer apparatus and a request-end computer apparatus. The provider-end computer apparatus is configured to: receive a request of data from the request-end computer apparatus; retrieve a data cluster designated in the request of data; execute a first fingerprint process on an unrequested part of the data cluster, which includes everything in the data cluster other than a requested part so as to obtain an unrequested data fingerprint; and return the requested part of the data cluster and the unrequested data fingerprint to the request-end computer apparatus.

Abstract: A method of verifying partial data based on collective certificate is provided. A provider-end computer apparatus receives a request of data, retrieves a data cluster, executes a fingerprint process on the unrequested part of the data cluster for obtaining an unrequested data fingerprint, and transfer the requested part of the data cluster and the unrequested data fingerprint to a request-end computer apparatus. The request-end computer apparatus retrieves a trusty collective data fingerprint, executes the fingerprint process on the requested part of the data cluster for obtaining a requested data fingerprint, merges the unrequested data fingerprint and the requested data fingerprint into a merged collective data fingerprint, and determines that the requested part is correct if the merged collective data is consistent with the trusty collective data fingerprint. The present disclosed example can effectively verify correctness of the requested part of data.

Abstract: A method of registration and access control of identity for third-party certification is provided. The method has steps of registration and steps of access control. The steps of registration have: controlling a user-end computer apparatus to retrieve an identity image of an identity document of a user; executing processes on the identity image for obtaining identity data; retrieving embedded identity data from the identity document; and configuring and registering the identity data if the data are matched with each other. The steps of access control have: controlling the user-end computer apparatus to verify user's identity upon reception of request of identity access, and generating and returning return identity data to a request-end computer apparatus.
