A digital escrow pattern for data services can include selective access for obscured data at a remote site or in a cloud service, distributing trust across multiple entities to avoid a single point of data compromise. Based on the pattern, a “trustworthy envelope” for any kind of payload enables curtained access through a variety of decorations or seals placed on the envelope that allow for a gamut of trust ranging with guarantees such as, but not limited to, confidentiality, privacy, anonymity, tamper detection, integrity, etc. Verifiable trust is provided through families of techniques that are referred to as wrapper composition. Multiple concentric and/or lateral transform wrappers or layers can wholly or partially transform data, metadata or both to mathematical transform (e.g., encrypt, distribute across storage, obscure) or otherwise introduce lack of visibility to some or all of the data, metadata or both. |
