Abstract: A method, system and computer program product for delivering a digital identity document. A request is received to purchase a digital identity document from a user by a system. An acquisition uniform resource locator (URL) with parameters corresponding to the identity of the user and the requested digital identity document is created and provided to the user. The user utilizes the received URL to communicate with an issuer to request the digital identity document. The system then receives the requested digital identity document in encrypted form from the issuer. The system then delivers the encrypted digital identity document to the user. In this manner, the system can deliver to the user an identity document in digital form that has been vetted as trusted in a secure manner thereby reducing the number of occurrences in providing improper identity documents as well as lessening the ability to generate falsified identity documents.

Abstract: A master digital copy of a registration is transmitted. The registration is proof that a physical object has been registered with a registration authority. A valid peripheral digital copy of the registration is received. The valid peripheral digital copy of the registration was made from the master digital copy of the registration and is incapable of being used to make other valid digital copies of the registration.

Abstract: An example operation may include one or more of connecting, by an identity server, to a blockchain configured to store an identity trait of a user, retrieving, by an identity server, the identity trait from the a blockchain, establishing, by the identity server, a trust group homomorphism digital signature algorithm (DSA) for the user associated with the identity trait based on a public key PK1, creating, by the identity server, a zero-knowledge proof function with a public key PK2 based on a DSA member of the trust group homomorphism for witness data, providing, by the identity server, the witness data to a challenger for the zero-knowledge proof function, and receiving, by the identity server, a validation of the user as a proved user based on execution of the zero-knowledge proof function based on the witness data.

Abstract: A laser light striping method and apparatus suitable for reading smoke and distance navigation during fire rescue. The laser light striping apparatus comprises at least a laser light emitting element and at least one optical element for creating at least one laser light plane. The method provides an optimized Gaussian distribution profile of power across a laser light plane to avail safe navigation by human in a turbid environment such as smoke/fire during fire rescue and limit blinding by light.

Abstract: The apparatus is designed to maximize the laser beam diffusion for the harsh environment of horticulture through a light optimization design. The light optimization design is an optical flat back which has a center area sized to the laser beam diameter transmission width with an optical diffusion surface surrounded with a mirror surface for an internal secondary mirror to the optical flat front. The center area optical diffusion surface back expands the laser beam transmission and the internal reflections are reflected by the secondary mirror surface through the front of the apparatus. The invention is designed to have the front surface of the apparatus exposed to the harsh environment of horticulture.

Abstract: A method, system and computer program product for privacy control. A unique identifier for each data element of a group of data elements (e.g., driver's license contains a group of data elements, such as name, driver's license number) is created. These identifiers may be stored along with documentation (e.g., label) of the associated data elements in a manifest file. Alternatively, the identifiers may be stored in a file outside of the manifest file. In this manner, by utilizing a data element identifier which corresponds to a random number, security of privacy information is improved as one would only be able to obtain such sensitive information by obtaining such an identifier. Furthermore, the user only needs to send the requested data elements, as opposed to all the data elements of the group of data elements, to the challenger. In this manner, the user is preserving the security of other privacy information.

Abstract: An example operation may include one or more of connecting to a blockchain configured to store an identity trait of a user, retrieving the identity trait from the blockchain, establishing a trust group homomorphism digital signature algorithm (DSA) for the user based on a private key, creating a zero knowledge succinct non-interactive argument of knowledge (zkSNARK) proof constructed based on a DSA of a trait in the trust group homomorphism DSA as witness data, and obtaining further trust information related to the user from the witness data.

Abstract: A first digital identification document is transmitted from an identification authority to a mobile device of an identified individual. This first digital identification document is digitally signed and includes a set of attributes about the identified individual. In the same manner, a second digital identification document is also transmitted to the identified individual's mobile device. The second digital identification document is also digitally signed but includes a different set of attributes about the identified individual. The identified individual is then confronted by a series of challengers, wherein each challenger requires a different amount of information about the identified individual. Based on the identity of each challenger, the identified individual selects an appropriate identification document and transmits it to the applicable challenger's device.

Abstract: The present invention relates to a method and apparatus for preventing the draining of power for an enclosed reusable battery system deployed for a rechargeable flashlight for shipping and storage.

Abstract: The apparatus is designed to maximize the amount of spatial coherence of light directed along a desired trajectory by an optical diffuser. The light optimization device contains a laser, a mirror with hole, and an optical diffuser against the mirror. The aperture enables light to travel through the mirror to the optical diffuser. The mirror reflects light that is internally reflected and refracted back from the optical diffuser traveling along suboptimal trajectories. As such, the reflected light is redirected towards the optical diffuser for increased spatial coherence output directed along a desired trajectory forward.

The LED chip is mounted in a surface of the circuit board facing the front heat sink, and arranged such that it aligns with the first hole and the lens. The laser light source is provided in the back heat sink and arranged such that it extends at least partially through the second and third holes.

Abstract: The method utilizes a passport identification number as an element of a homomorphic encryption used to stamp a passport with country entry/exit data to form a digital representation of a subset of information in the passport. As a result, exchange of the digital representation is permitted to allow a selective transfer of information without exposing a user-sensitive passport identification number. The homomorphic encryption comprises a support for exposing a trusted photo and a trusted group containing country travel entry and exit information. The digitally signed passport stamp may then be used to provide verification of the individual by ensuring linkage to that user's passport. The individual's identity and passport verification may occur unconnected, i.e., without having to connect to a central database.
