Abstract: The present disclosure relates to secure and verifiable storage and retrieval of data, in particular in the context of product tracking. According to one aspect there is provided a computer-implemented verifiable data storage method comprising: receiving a product serial number; receiving an account identifier; producing a non-invertible hash by operating on the product serial number and the account identifier; and causing the hash to be written to a secure distributed data store. According to another aspect there is provided a computer-implemented verification method comprising: receiving a product serial number; receiving an account identifier; producing a non-invertible hash by operating on the product serial number and the account identifier; searching a secure distributed data store for the hash; and depending on a result of the searching, providing confirmation or denial of the hash's presence in the secure distributed data store.

Abstract: A method for triggering payment transactions through predetermined events identified using a blockchain includes: receiving, at a first system, trigger data including a first account identifier, second account identifier, and trigger event values; receiving, at the first system, blockchain data values, each including a hash value; identifying, by the first system, a match between a specific blockchain data value and a specific trigger event value based on the hash value; transmitting, by the first system, a notification message to a second system including the first account identifier and second account identifier; identifying, by the second system, a first payment identifier using the first account identifier and a second payment identifier using the second account identifier; and initiating, by the second system, a payment transaction for payment from a transaction account associated with the first payment identifier to a transaction account associated with the second payment identifier.

Abstract: A method is provided for communicating a non-speech message as audio from a first device to a second device such that information can be passed between the first and second device. The method includes: encoding the non-speech message as a dissimilar speech message having a plurality of phonemes; transmitting the speech message over one or more audio communications channels from the first device; receiving the speech message at the second device; recognizing the speech message; and decoding the dissimilar speech message to the non-speech message. By using existing audio functionality, and the increasingly more reliable voice recognition applications, an improved method is provided for sharing complex data messages using commonly available communication channels.

Abstract: A method for verification of a pruned blockchain transaction includes: receiving, by a receiver of a computing device, a subset of blocks included in a plurality of blocks comprising a blockchain, wherein each block includes one or more blockchain data values; receiving, by the receiver of the computing device, an authentication code; identifying, by a processor of the computing device, a plurality of data chunks in the subset of blocks using the authentication code, where each data chunk of the plurality of data chunks is included in one of the one or more blockchain data values in a block of the subset of blocks; decoding, by the processor of the computing device, a transaction value using at least the identified plurality of data chunks and a fountain code algorithm; and verifying, by the processor of the computing device, the decoded transaction value.

Abstract: A method for conveying auditable information regarding provenance of a product that is cryptographically accurate while retaining complete anonymity of product and participant on a blockchain includes: receiving a product identifier; generating a digital token by applying a hashing algorithm to the product identifier; generating an entry value by applying the hashing algorithm to a combination of an event identifier and the digital token; generating a digital signature by digitally signing a data package using a private key of a cryptographic key pair, where the data package includes at least a blockchain address, the event identifier, and the digital token; and transmitting the blockchain address, the digital signature, and the entry value to a node in a blockchain network.

Abstract: A natural language processing system and method includes a computing device that applies a phonetic code algorithm to a received proper name uttered by a user and determines from a phonetic name database whether multiple different spellings of the name exist. The computing device recognizes an utterance of the user providing a natural language cue regarding the correct spelling of the name or provides a voice prompt to the user including a natural language cue regarding the correct spelling of the name, and converts the name to text including the correct spelling.

Abstract: Machine learning vision systems rely on very large numbers of training images to learn to recognize particular shapes and configurations of shapes. Traditionally, such datasets of training images needed to be selected and tagged (or labelled) manually. To recognize a particular object, such as a dog or vehicle, under realistic settings with an acceptable degree of reliability, may require data sets of thousands of images per object class.
To improve this, a method is provided to generate datasets with a multiplicity of corresponding images are generated using a 3D rendering engine using a plurality of lighting arrangements and a plurality of views. Artefacts may also be introduced. In this way, very large data sets become feasible, with a variable degree of correspondence in each data set.
