DELIVERY PACKAGE DAMAGE DETECTION USING PHOTOGRAMMETRY MODELS

NºPublicación: US2021319543A1 14/10/2021

Solicitante:

IBM [US]

Resumen de: US2021319543A1

In order to detect possible damage to a delivered product, a set of first images of the product is created prior to delivery which are used to generate a first 3D photogrammetry model, and a set of second electronic images are created after delivery which are used to generate a second 3D photogrammetry model. The two models are then compared to determine whether there is a sufficient deviation to conclude the product has been damaged. The comparison is performed by a cognitive system trained with samples of before/after photogrammetry model pairs each associated with either a damaged condition or a not damaged condition. The baseline photogrammetry model is part of a blockchain record and the recipient photogrammetry model is added to the blockchain record. Intermediate photogrammetry models can also be built where there is more than one shipper along the delivery route to assign liability to the proper party.

Solicitante:

DUVON CORP [US]

Resumen de: US2021319436A1

In a blockchain networking environment, a wallet keying system creates a private key that is used for authorizing user transactions while negating the need for the private key to be hosted on a user device or in a user application such as a blockchain wallet. The private key is fragmented and stored in a distributed fashion to prevent unauthorized access. To ensure scalability and network performance, a shard system allows the movement of users and user applications and tools within a decentralized and distributed blockchain network to enable better network balance and utilization of available resources at the local node level. A network provisioner is permitted to impose and adjust restrictions applied to a wallet or on blockchain tokens with the restrictions either being adjusted based on milestones and measured parameters or manually.
