Abstract: A monitoring service monitors performance of an authentication application that authenticates a user or service and securely communicates a status of the authentication application to a service application providing a software service. The monitoring service generates a token using a private key. The token is stored in a secure datastore writable only by the monitoring service and is also provided to the service application. The service application validates a signature of the token using a public key and determines an authenticity of the token by comparing the received token to the stored token in the secure datastore. In doing so, there is a high degree of confidence that the token, or an associated encrypted message, originated from the monitoring service and properly identifies the status of the authentication application.

Abstract: A computer implemented method and apparatus for a memory efficient approach for decoding progressive JPEG images. The method comprises (a) accessing a progressive JPEG image, wherein the progressive JPEG image comprises a plurality of compressed scans and wherein each scan in the plurality of scans comprises a plurality of compressed rows of image data; (b) decompressing not more than half of the compressed rows of each scan in the plurality of scans into a memory buffer; (c) copying a remaining plurality of compressed rows of each scan in the plurality of scans into a plurality of small memory buffers; (d) decoding, in place, the decompressed rows in the memory buffer; and (e) repeating steps (b)-(d) until a predefined number of rows are remaining in the plurality of small memory buffers, at which time the remaining rows are decompressed and decoded.
