Abstract: A replaceable item for a host device includes a non-volatile memory and logic. The non-volatile memory stores passwords or authentication values, and/or a cryptographic key. The logic permits retrieval of a predetermined maximum number of the passwords from the non-volatile memory to authenticate the replaceable item within the host device. The predetermined maximum number of the passwords is less than the total number of the passwords.

Abstract: A printer cartridge includes a memory device and at least one compressed color table stored on the memory device. A compressed color table includes a losslessly compressed neutral axis, a number of nodes that correspond to seed color table nodes and a number of delta nodes that correspond to a number of delta tables. The number of delta tables indicate differences between interpolated color table nodes and corresponding actual color table nodes.

Abstract: A replaceable printer component includes a memory device to store a tag encryption mask and data. The data is stored in a plurality of blocks of the memory device wherein each block is defined by a tag. The tag encryption mask indicates an encryption status of each block of the memory device defined by the tag. The replaceable printer component includes a communication link to communicatively link the memory device to a printer controller when the replaceable printer component is installed in a printing system. The tag encryption mask is stored within a header of the memory device. Each tag defines a type and a length of the data stored in the blocks.

Abstract: In some examples, a device authenticates a first consumable product installed in the device, sends a first identifier of the authenticated first consumable product over a network to an engine, receives, over the network from the engine, a list of identifiers for consumable products classified as non-authentic, and in response to installation of a second consumable product in the device that stores an identifier in memory, determines whether the identifier of the second consumable product matches one of the identifiers in the received list of identifiers.

Abstract: Authenticating a consumable product based on a remaining life value includes determining whether an identifier stored in memory of a consumable product is listed in a device history and concluding that the consumable product is not authentic if the device is determined to have used the consumable product previously based on the device history and a current remaining life value associated with the consumable product indicates less use than a recorded remaining life value for the consumable product associated with the identifier in the device history.
