  • Publication number: 20240077350
    Abstract: An optical detection device includes a first linear light source, a second linear light source, an optical sensor array and a processor. The first linear light source is adapted to project a first long strip illumination beam onto the target container. The second linear light source is adapted to project a second long strip illumination beam onto the target container, and the second long strip illumination beam is crossed with the first long strip illumination beam. The optical sensor array is adapted to receive a first long strip detection beam and a second long strip detection beam reflected from the target container. The processor is electrically connected to the optical sensor array. The processor is adapted to analyze intensity distribution of the first long strip detection beam and the second long strip detection beam to acquire a relative distance between the optical sensor array and the target container.

  • Patent number: 11271931
    Abstract: Techniques for securely generating and using a “fingerprint” for authentication. A server computer receives a first data set from a user device (including a first fuzzy hash of first user data on the user device). The server computer generates a first fingerprint value based on the first data set. The server computer detects an event corresponding to a user in association with the user device. The server computer identifies a baseline fingerprint value (generated based on a baseline fuzzy hash of user data on the user device). The server computer compares the first fingerprint value to the baseline fingerprint value to generate a similarity score. The server computer may determine that the similarity score exceeds a threshold value but does not represent an exact match, and, based on the similarity score, authenticate the user and update the baseline fingerprint value based on the first fingerprint value.

  • Patent number: 11106476
    Abstract: A helper SDK embedded in a native application performs local operations on behalf of a web application affiliated with the helper SDK. The helper SDK may perform security functions such as fingerprint or face biometric verifications as well as access device-specific hardware such as a camera or secure memory. The web application may use an 0Auth technique for access and refresh tokens. In a transaction system, when a user is confirmed via the security function, order details are passed to the web application with a refresh token and ciphertext confirmation data is returned to the native application for completion of the transaction.

  • Publication number: 20210166226
    Abstract: A method and system for authentication through deep-links is provided. A communication device can provide a credential to a remote server computer as part of an authentication process. The remote server computer can challenge the communication device by transmitting a deep-link containing a one-time passcode to the communication device. The communication device can activate and parse the deep-link to determine the one-time passcode. The one-time passcode can be transmitted back to the remote server computer by the communication device. The remote server computer can verify that received one-time passcode matches the sent one-time passcode in order to complete the authentication process.

  • Publication number: 20170262708
    Abstract: A logic control circuit controls a remote pan tilt zoom (PTZ) camera by transmitting commands and displaying the resulting image on a 3D touch sensitive display. When pressure is measured at two or three locations of the display, a new centerpoint is determined. The relative force applied at the pair of locations causes a determination of desired direction and desired rate of change of zoom or roll. A bounding box is added to the presently displayed image and commands are transmitted to the PTZ camera to fulfill the desired change in orientation and image size. Several limits and interrupts are set to stop the zooming process. The process includes measuring and comparing the force applied incident to a 3D touch user interface integrated with a display at two locations.
