Abstract: One example method includes receiving, at a target, a migrated container, the container being migrated by a source, retrieving, by the target, a first container hash from an immutable distributed ledger, the first container hash being created at the source by hashing the container, and the first container hash being written by the source to the immutable distributed ledger, hashing, at the target, the container to create a second container hash, writing, by the target, the second container hash to the immutable distributed ledger, and determining, by the target, whether the first container hash and the second container hash match, and a failure of the first container hash to match the second container hash indicates that in-flight tampering of the container has occurred while the container was migrating from the source to the target.

Abstract: Automatic image splicing with metadata retention is disclosed. An image is retrieved from an image repository and checked for missing or invalid pixels. Additional images are retrieved from the image repository based on the missing or invalid pixels. Valid pixels from the additional images are used to replace the missing or invalid pixels in the original image. The resulting spliced image is complete. Metadata from all images represented in the spliced image are included in a metadata lineage associated with the spliced image.

Abstract: Techniques described herein relate to a method for managing transactions in a distributed ledger. The method includes obtaining a transaction request from a client; in response to obtaining the transaction request: verifying client information associated with the client and the transaction request; anonymizing the transaction request to generate an anonymous transaction request; updating client payload mappings based on the anonymous transaction request; shuffling the anonymous transaction request with a batch of requests to generate a shuffle index; assigning the batch of requests to virtual users to generate virtual user assignments; and processing the transaction request using the batch of requests.

Abstract: A fragment and shuffle erasure coding operation is disclosed. In a transformative operation, encrypted fragments are generated from an input file. The transformative operation includes one or more iterations of chunking the file and mixing the chunks to generate a mixed sequence. The mixed sequence is sliced into encrypted fragments. The encrypted fragments are shuffled in a storage system such that physical locations of the encrypted fragments change over time.

Abstract: A system and method for generalizing the content in a formatted document permits a group with multiple elements to be processed rapidly even if the number of elements in the group changes over time.
