Abstract: The present teaching relates to method, system, medium, and implementations for authenticating a user. A first request is received to set up authentication information with respect to a user, wherein the first request specifies a type of information to be used for future authentication of the user. It is determined whether the type of information related to the user poses risks based on a reverse information search result. The type of information for being used for future authentication of the user is rejected when the type of information is determined to pose risks.

Abstract: A method of manufacturing an osteoinductive osteoimplant is provided which comprises the steps of: demineralizing part or all of at least one surface of a monolithic section of cortical bone to a depth of at least about 100 microns; and, configuring the monolithic section of cortical bone to provide an osteoimplant possessing an outer surface possessing at least one demineralized zone and a non-demineralized zone. An implant produced according to the above method demonstrates improved osteoinduction without producing any clinically significant reduction of strength in critical regions of the osteoimplant.

Abstract: An osteoimplant is provided which comprises a coherent aggregate of elongate bone particles, the osteoimplant possessing predetermined dimensions and shape. The osteoimplant is highly absorbent and sponge-like in nature. Also provided herein are a method of fabricating the osteoimplant and a method of repairing and/or treating bone defects utilizing the osteoimplant.
