Abstract: A host based security system for a computer network includes in communication with the network a credential host that is operative in concert with a local computer and a destination site. The destination site has a credential authentication policy under which credentials associated with the local computer upon being authenticated authorizes data to be communicated between each of the destination site and the local computer during a communication session over the network. The credential host stores the credentials to be used by the destination and is operative to transmit the credentials onto the network in response to a request received from the local computer. The destination site upon the credentials being received and authenticated thereat is operative to transmit session information onto the network. The local computer is then operative to commence the communication session upon receipt of said the information.

Abstract: The present invention provides monopolar acetabular liners (32, 54) that can enclose a femoral head (14) to form a hip replacement prosthesis (30, 50), wherein the liner (32, 54) has a rim (34) that creates an orifice, wherein the orifice has a diameter that is smaller than the diameter of the femoral head (14), and wherein the liner (32, 54) encompasses greater than 50 percent of the volume of the head (14), wherein a constraining ring (56) can be used in conjunction with the monopolar constrained acetabular liner (32, 54) to provide additional support for the femoral head (14) to stay with the acetabular liner (32, 54) and avoid dislocation. Assemblies and complete prosthetic replacements are also provided. Liners (32, 54) and constraining rings (56) having no, one or more recesses (36) also are provided.

Abstract: A medical prosthesis for use within the body which is formed of radiation treated ultra high molecular weight polyethylene having substantially no detectable free radicals, is described.

Abstract: A method for authenticating a user based on a plurality of authentication factors includes a step of receiving a first authentication factor from a first communication device of the user. The first authentication factor includes a password. The method includes a step of receiving a second authentication factor. The second authentication factor comprises at least one of at least one device identifier of the first communication device of the user and data transmitted to or received from a second communication device of the user. The method also includes a step of authenticating the user based on at least the received plurality of authentication factors.

Abstract: A system and method authenticates a user if the user is associated with a certificate on a device the user is using to communicate, even if other users are also associated with the same certificate and/or the user is associated with other certificates on other devices.

Abstract: A system and method authenticates an e-mail message containing a code that may be sent as part of an advertising campaign. The code is a hashed hash result of a combination of the e-mail address to which the message was sent and a pass phrase for the campaign, along with an identifier of the campaign. To authenticate the message, the user supplies the user's e-mail address and the code and the system and method parses the code to identify the campaign identifier and hashed hash result, looks up the pass phrase using the campaign identifier, hashes the campaign identifier and e-mail address and hashes that hash result. If the hashed hash results match, the system and method indicates the message is authentic and otherwise, indicates the message is not authentic.

Abstract: A system and method allows a user to authenticate a communication from a computer system, a computer system to authenticate a user, or both. When a user requests a web page from the web site, customization information that is recognizable to the user is provided to allow the user to authenticate the web site. A signed, encrypted persistent file stored on the user's computer system or installed on a different computer system, or a trusted computing subsystem allows the web site to authenticate the user. If the user is using a system that will not allow that user to be authenticated, the user may instruct the system to continue providing information without the user's customization information. The system and method may be used to allow the user to authenticate an e-mail message or its source, and Flash movies or other computer code may be used if the user's e-mail client does not employ cookies.
