  • Publication number: 20220210156
    Abstract: A process running on client devices intercepts requests destined for an identity provider (“IdP”) system and injects a digital signature corresponding to a user associated with the request. In order to reduce or eliminate the burden on providers of the applications or other resources used by the users, the organization providing the IdP system may also provide components that run locally on the client devices of users and integrate with the users' applications. For example, in one embodiment code of the IdP system is run within a container of an application to handle communication with the IdP system. Additionally, code of the IdP system is run as a local process that handles request interception and digital signature injection. For client devices not supporting the use of the local process, a separate verifier application of the IdP can be run locally and allow interactively performing authentication via a user interface.

  • Publication number: 20220150069
    Abstract: An authentication system facilitates a transfer of enrollment in authentication services between client devices. The authentication system enrolls a client device in authentication services to enable the client device to be used for authenticating requests to access one or more services. As part of enrolling the client device, the authentication system receives authentication enrollment information for the client device that is associated with one or more authentication credentials securely stored on the client device (e.g., a multi-factor authentication (MFA) certificate). The authentication system facilitates one or more processes for transferring the enrollment from an enrolled client device to a non-enrolled client device that limit the number and complexity of actions performed by the user.

  • Patent number: 9298868
    Abstract: A technique for generating pushdown data comprises performing logical pushdown of circuit elements and nets and detecting physical pushdown based on partition boundary crossings. Geometry associated with one logical level may be used as a keep-out region for the same physical layer when generating physical design of a different logical level. The technique may advantageously enable concurrent design in both top-level and low-level physical design phases, thereby reducing overall design cycle time in developing an integrated circuit.

  • Publication number: 20110144181
    Abstract: Solid pharmaceutical compositions containing atorvastatin are disclosed. The compositions include a solid dispersion of amorphous atorvastatin and one or more optional pharmaceutically acceptable excipients. The solid dispersion is prepared by mixing crystalline atorvastatin with a melt-processible polymer and an optional stabilizer and an optional plasticizer at a temperature sufficiently high to soften or melt the polymer and to melt or dissolve the crystalline atorvastatin in the polymer, thereby forming a dispersion of amorphous atorvastatin.
