Technologies are shown for controlling a transaction on a blockchain. A first block is created on a blockchain for a transaction involving a seller entity associated with a first key, a buyer entity associated with a second key, and an intermediary entity associated with a third key. Funds for the transaction are associated with the first block. A second block storing refund code is created and linked to the first block. The refund code is executable to refund the funds when a seller digital signature using the first key and/or an intermediary digital signature using the third key are received. A third block storing payment code is created and linked to the first block. The payment code is executable to transfer the funds when a buyer digital signature using the second key and/or an intermediary digital signature using the third key are received.

Technologies are shown for secure management of personal information data involving storing personal information data in a personal information data block and committing the personal information data block to a personal information data blockchain and authorizing access to the personal information data by a platform entity by storing a platform identifier corresponding to the platform entity in authorized access data. An access request is received from the platform entity that includes the platform identifier for the first platform entity. If the platform identifier is verified to be in the authorized access data, the personal information data is obtained from the personal information data blockchain and returned to the platform entity. In some examples, the authorized access data includes permissions that identify portions of the personal information data that the platform entity can access. In other examples, the authorized access data is secured on an authorized access data blockchain.

Technologies are shown for content distribution on a blockchain. An access request is received for digital content owned by a first entity and associated with one or more blocks of a blockchain. The access request is associated with a second entity. A current use condition associated with the second entity is verified to satisfy a use requirement conditions attribute defined by at least one of the one or more blocks of the blockchain. Responsive to verifying the current use condition satisfies the use requirement conditions attribute, the second entity is provided access to the digital content.

In various example embodiments, a system and method for determining a crowd response for a crowd are presented. One method is disclosed that includes receiving an audio signal that includes concurrent responses from two or more respondents, determining the concurrent responses from the audio signal without regard to the identity of the respondents, and generating a crowd based on the concurrent responses.

According to example embodiments, an Image View Aggregator identifies a frontal view of an item within an image. The Image View Aggregator identifies at least one reflection view of the item within the image. Each reflection view of the item having been captured off a corresponding reflective physical surface. The Image View Aggregator extracts the frontal view of the item and each reflection view of the item from the image. The Image View Aggregator generates a representation of the item based at least on the extracted frontal view of the item and each extracted reflection view of the item.

Methods and systems for generating new product images are disclosed. In one aspect, a method includes identifying, via hardware processing circuitry, a template for a category of products, the template defining locations of attributes of products belonging to the category, identifying, via the hardware processing circuitry, common attributes of products of the category based on the template, averaging, via the hardware processing circuitry, corresponding pixel values across images representing the products having the common attributes, generating, via the hardware processing circuitry, a new product image representing a new product based on the averaged pixel values; and generating, via the hardware processing circuitry, a modified new product image by varying attributes of the new product based on the locations of the attributes defined by the template.

Technologies are shown for controlling a transaction on a digitally stored blockchain by creating a contract data block for a transaction involving entities and by event code executed after receipt of digital signatures from the entities. A refund transaction may be digitally signed by entities and linked to the contract block within the blockchain. A payment transaction block may also be digitally signed by entities and linked to the contract block. Code authorized to execute by the blocks executes based on receipt of digital signature events.

Technologies are shown for content distribution on a blockchain involving generating a content distribution data block on a content distribution data blockchain, that stores digital content, data identifying the digital content, an owner identifier, an access holder identifier, and a use conditions attribute for identifying use requirements for the digital content. A use requirement is defined in the use conditions attribute. An owner identified in the owner identifier sets the access holder identifier to an identifier for a user entity. An access request is received from the user entity and, in response, whether a current use condition of the user entity satisfies the use requirement in the use conditions attribute is verified. If it is verified that the current use condition of the user entity satisfies the use requirement in the use conditions attribute, the digital content is distributed to the first user entity.

Technologies are shown for secure management of a data file secured on a data file management blockchain that involve generating a genesis block for a data file management blockchain that contains a data file to be managed and signing the genesis block to commit the genesis block to the data file management blockchain. One or more transaction data blocks are generated for the data file management blockchain that each include a modification to the data file and the blocks are signed to commit them to the blockchain. In some examples, the modifications describe changes to the data file and the transaction data blocks are traced to the genesis block and a current data file generated by applying the modifications on the transaction data blocks to the data file in a sequence determined by an order of the one or more transaction data blocks in the data file management blockchain.

An attribute correlation system reduces network traffic and processing cycles associated with impromptu item selections by generating attribute preference models based on disparate attribute spectrums. The attribute correlation system deploys the attribute preference models to select individual items from various disparate 'candidate item categories.' Generally described, the attribute preference models facilitate analyzing item sets across a wide variety of disparate 'candidate' item categories to preemptively identify individual items for a user. In this way, the individual items may be identified and, ultimately, selected for the user even absent any indication that the user has searched for otherwise identified these items or even other items from within the disparate &#x201c;candidate&#x201d; item categories. The &#x201c;candidate&#x201d; item categories may be determined to be disparate from one another based on a relationship void existing such that predefined relationships are missing between these &#x201c;candidate&#x201d; item categories.

Methods, systems, and apparatus for monitoring a sound are described. An audio signal is obtained and the audio signal is analyzed to generate an audio signature. An object type is identified based on the audio signature and an action corresponding to the object type is identified.
