  • Publication number: 20070094498
    Abstract: A single sign-on technique allows multiple accesses to one or more applications or other resources using a proof-of-authentication module operating in conjunction with a standard authentication component. The application or other resource issues an authentication information request to the standard authentication component responsive to an access request from the user. The application or other resource receives, responsive to the authentication information request, a proof-of-authentication value from the standard authentication component, and authenticates the user based on the proof-of-authentication value. The standard authentication component interacts with the proof-of-authentication module to obtain the proof-of authentication value. The proof-of-authentication module is configured to generate multiple proof-of-authentication values for authentication of respective access requests of the user.

  • Publication number: 20060177056
    Abstract: Techniques for secure generation of a seed for use in performing one or more cryptographic operations, utilizing a seed generation protocol carried out by a seed generation client (110c) and a seed generation server (110s). The seed generation server (110s) provides a first string to the seed generation client (110c). The seed generation client (110c) generates a second string, encrypts the second string utilizing a key (216), and sends the encrypted second string to the seed generation server (110s). The seed generation client (110c) generates the seed as a function of at leas the first string and the second string. The seed generation server (110s) decrypts the encrypted second string (222) and independently generates the seed as a function of at least the first string an the second string.

  • Publication number: 20050166263
    Abstract: In a system for disconnected authentication, verification records corresponding to given authentication token outputs over a predetermined period of time, sequence of events, and/or set of challenges are downloaded to a verifier. The records include encrypted or hashed information for the given authentication token outputs. In one embodiment using time intervals, for each time interval, token output data, a salt value, and a pepper value, are hashed and compared with the verification record for the time interval. After a successful comparison, a user can access the computer. A PIN value can also be provided as an input the hash function. A portion of the hash function output can be used as a key to decrypt an encrypted (Windows) password, or other sensitive information.

  • Patent number: 4099271
    Abstract: A lightweight costume head having a hollow foundation constructed from thin slabs of foamed, elastomeric sections adhered together having an access opening and generally a cloth covering enveloping said foundation is described. The foundation generally has eye openings and may have a nose-mouth opening. The foundation comprises at least five sections cut from the flat slab of a foamed elastomer to form a head shape, frequently a spherical shape from identical sections adhered along their edges.

  • Patent number: 4035214
    Abstract: Process for transferring overlayed multiple ink patterns from the surface of a release blanket to a receiving surface on a container or other formed article being printed. A substantially transparent film is first formed on the release blanket, with each ink pattern being printed sequentially over this release film. Proper printing on the release film without picking the release film or previously applied ink films is obtained when certain adhesive and cohesive relationships are maintained between the ink films and the release film. An adhesive film may be formed on the article to be printed, or it may be formed over the ink films and the release film on the release blanket. The receiving surface on the article to be printed is brought into contact with the films on the release blanket, with a resulting total transfer of the films on the blanket to the surface of the article.

  • Patent number: 3978260
    Abstract: A support member, for inclusion inside a film-wrapped package of moist and greasy food, comprising a semi-rigid thermoplastic core member printed on both sides with opaque ink distributed in substantially equal amounts on the two sides of the core and having a transparent protective overcoating of a polyolefinic resin or a varnish superposed on the printed core layer.
