  • Patent number: 10521618
    Abstract: The present disclosure describes apparatuses and techniques for secure root key provisioning. In some aspects, a stream of entropy bits is generated based on analog noise. From the stream of entropy bits, entropy symbols are constructed and used to modulate bits of a unique chip identifier to provide a block of modulated symbols. A hash digest of the block of modulated symbols is then calculated to generate a device-level root key. This device-level root key written to a write-only register of a one-time programmable (OTP) memory controller for subsequent writing into an OTP memory. By so doing, unauthorized entities can be prevented from accessing the device-level root key during the secure key provisioning process.

  • Patent number: 9159008
    Abstract: Embodiments of the present disclosure provide a method for estimating usage of a print substance. The method comprises receiving a plurality of pixels of a page to be printed, and generating, for one of the plurality of pixels, a look-up address based on (i) pixel bits of the one of the plurality of pixels, and (ii) pixel bits of one or more other pixels proximal to the one of the plurality of pixels. The method further comprises estimating an amount of print substance deposited on the page at a location associated with the one of the plurality of pixels based on reference to a print substance amount in a table of print substance amounts, wherein the reference to the print substance amount in the table is made using the look-up address.

  • Patent number: 9064204
    Abstract: Some of the embodiments of the present disclosure provide an apparatus for processing a starting image, comprising: a first unit configured to provide starting pixel data from a selected portion of the starting image, wherein the selected portion is less than an entirety of the starting image; and a second unit configured to receive the starting pixel data from the first unit and to selectively provide to a look up table (LUT) an address of replacement pixel data for at least a pixel of the selected portion of the starting image. Other embodiments are also described and claimed.
