Embodiments of the present invention address deficiencies of the art in respect to privacy data management and provide a novel and non-obvious method, system and computer program product for trusted statement verification for data privacy. In one embodiment of the invention, a method for trusted statement verification for data privacy can be provided. The method can include deducing a claim from an attribute for personal data for an end user, receiving a request from a personal data consumer to vouch for an assertion based upon the attribute, comparing the assertion to the claim, and providing a voucher for the assertion to the personal data consumer on behalf of the end user if the claim supports the assertion without revealing the attribute to the personal data consumer.

Trusted statement verification for data privacy

A sending entity creates a structured document and communicates it to a receiving entity includes a transform to ensure document elements are not moved during communication. The structured document comprises a root element and a set of child elements. A child element is protected by a digital signature, prior to being positioned within the document. This element includes a sending entity security policy. The receiving entity includes a transform that determines whether the signed element is in a given position within the received document. The transform evaluates the data string against a set of ancestor elements of the signed element to determine whether the signed element is in the given position. If so, the transform preferably outputs the signed element itself. If the transform determines that the signed element has been moved, however, preferably it outputs a given value other than the signed element.

Methods, systems, and products are disclosed in which generating evidence of web services transactions are provided generally by receiving in an ultimate recipient web service from an initial sender a request, the request containing a proof of message origin ('PMO'). The PMO contains an element addressed to the ultimate recipient web service and the element bears a first signature, the first signature having a value. Embodiments also include authenticating the identity of the initial sender; creating a proof of message receipt ('PMR') including signing the value of the first signature; sending the PMR to the initial sender, receiving, by the initial sender, the PMR; and saving, by the initial sender, the PMR.

Generating evidence of web services transactions

A method for single sign-on with established federation includes triggering a single sign-on operation from a first service to a second service, retrieving, by the first service, an associated federation key and pseudo identification for a user agent, generating, by the first service, a token signed with a federation key for the user agent based on the pseudo identification, redirecting, by the first service, the user agent to the second service, wherein the user agent transfers the token to the second service, verifying, by the second service, the token and determining an associated identification in the second service, and returning, by the second service, a resource to the user agent.

A machine-implemented method for signing a JSON message begins by constructing a reference element for each data object in the JSON message. The data object is identified by a reference identifier that includes a pointer to a digest method, and a digest generated by applying the digest method to the data object. Then, a signature information element is constructed for reference elements corresponding to data objects in the message. The signature information element includes a pointer to a signature method, as well as one or more reference elements, or a canonical form of the one or more reference elements. Then, a signature element is constructed that includes the signature information element, and a signature value generated by applying the signature method to the signature information element. The signature enables a sending entity to generate a digest on a JSON message and to secure the digests using a signing key.

A method for malware detection, wherein the method includes: utilizing a hardware based program flow monitor (PFM) for embedded software that employs a static analysis of program code; marrying the program code to addresses, while considering which central processing unit (CPU) is executing the program code; capturing an expected control flow of the program code, and storing the control flow as physical address pairs of leaders and followers (LEAD-FOLL pair) in a Metadata Store (MDS) within the PFM; monitoring control flow at runtime by the PFM; and comparing runtime control flow with the expected control flow.
