  • Patent number: 10484602
    Abstract: Approaches are described for constructing a single camera by combining an array (or other arrangement) of multiple smaller and lower resolution cameras. Each of the smaller cameras is aimed in a different direction in order to provide a wider angle and higher resolution field of view (FOV) for the resulting composite camera. Images captured by all of the cameras in the array can be stitched together using software to produce a single composite photograph. This construction method can enable the camera unit to be thinner and potentially cheaper in construction costs than an equivalent single-piece camera that has been conventionally implemented in portable devices.

  • Patent number: 9787568
    Abstract: A physiological test credit method determines if test credits are available to the monitor and checks if a Wi-Fi connection is available. If test credits are less than a test credit threshold, the monitor connects to a test credit server, processes server commands so as to download test credits and disconnects from the server. In various embodiments, the monitor is challenged to break a server code, the server is challenged to break a monitor code. The server validates monitor serial codes, and saves monitor configuration parameters.

  • Patent number: 9779227
    Abstract: A system for controlling access to secured resources using a security token having a hologram embossed thereon is provided. A key is split into a user key and a complimentary key based on a mask, wherein key values in the user key correspond to idle state values in the complimentary key and vice versa. The user key is used to generate a user key array, that is used to generate a three-dimensional virtual image that is holographically embossed onto a security token. The hologram is merged with a corresponding hologram for the complimentary key and the combination compared to an image of an ensemble of the key. The combination can be mergers of images or extractions of holograms. If a match is found, within a tolerance, an access grant signal is sent to the secure resources, thereby securing the resources based on presence of the security token.

  • Patent number: 9613217
    Abstract: Confidential content within a file is masked for display on a flexible display device. A legend relating the masking to the confidential content is displayed in a hidden area created by bending the flexible display device. The flexible display device monitors secondary users and their gaze towards the flexible display device and the hidden area to determine if unauthorized secondary users can see the display and hidden area of the flexible display device.

  • Patent number: 9596234
    Abstract: Methods and systems for providing access to a secure computing device are disclosed. A security device is used to generate a one-time password, a sequence of symbologies, and location information. The security device transmits the password, sequence and location information to the secure computing device for storage and displays the password and sequence to a user. A user device provides a password to the secure computing device in order to obtain access. The secure computing device compares the password with the stored one-time password to verify the user of the user device and sends the sequence to the user device in response. The user or user device verifies the sequence of symbologies to confirm the secure access. The location information may be used to detect fraudulent accesses to the user account.

  • Patent number: 9589111
    Abstract: A trusted rendering system for use in a system for controlling the distribution and use of digital works. A trusted rendering system facilitates the protection of rendered digital works which have been rendered on a system which controls the distribution and use of digital works through the use of dynamically generated watermark information that is embedded in the rendered output. The watermark data typically provides information relating to the owner of the digital work, the rights associated with the rendered copy of the digital work and when and where the digital work was rendered. This information will typically aid in deterring or preventing unauthorized copying of the rendered work to be made. The system for controlling distribution and use of digital works provides for attaching persistent usage rights to a digital work. Digital works are transferred between repositories which are used to request and grant access to digital works.

  • Patent number: 9563517
    Abstract: A computer implemented method, system, and program product for creating snapshots instructions at a replication site, the method comprising determining the differences between a first snapshot at a first time of a LUN and a second snapshot at a second time of the LUN, determining the differences between the second snapshot and a third snapshot at a third time of the LUN, creating a redacted snapshot of the second snapshot wherein the redacted snapshot contains pointers to the first snapshot for the common data in the first snapshot and the second snapshot; wherein the redacted snapshot contains pointers to the third snapshot for common data in the second snapshot and the third snapshot; and further wherein the redacted snapshot stored data that is not present in the first snapshot and is not present in the third snapshot.

  • Patent number: 9419795
    Abstract: Disclosed is a method for performing secure communication using a digital device. The method includes outputting a light pattern using a radiator of a proximity sensor unit; and detecting the proximity of an object using the proximity sensor unit. Further, the method includes, when the object is in proximity within a predetermined distance range, extracting key generation information for the secure communication using the light pattern outputted from the radiator; generating a security key using the key generation information; and performing the secure communication with an external device using the generated security key.

  • Patent number: 9418215
    Abstract: An optical security device can be used to view sensitive information provided in an obscured format via a potentially untrusted and/or compromised computer. The techniques described herein enable use of untrusted computers for access to sensitive information. The optical security device employs one or more forms of visual cryptography such as spatial cryptography and/or temporal cryptography in some instances via a programmable mask and/or a programmable color filter to reveal sensitive information that is provided in an obscured form by a potentially untrusted computer.

  • Patent number: 9396310
    Abstract: Methods, non-transitory computer readable media and apparatuses for decrypting an image are disclosed. For example, a method captures a portion of an encrypted image and decrypts the portion of the image using a decryption key. The portion of the image contains partial information for an adjacent portion of the image. The method then displays the portion of the image that is decrypted and also displays the adjacent portion of the image using the partial information for the adjacent portion of the image. Another method includes capturing a first portion of an image that is encrypted using a first key and a second key, decrypting the first portion of the image using a first key and displaying the first portion of the image that is decrypted.
