The central computer system converts the consumer's identifying information into an identification code that conceals the identity and stores it along with contact information for the consumer's computer system. When a computer system on the central computer system's network transacts with an entity that uses the consumer's identification code, the central computer system contacts the consumer's computer system, allowing the consumer to stop the transaction if it is unauthorized. Because only the identification code is used to protect the consumer, the consumer's original identity is fully protected.

The trained entry classifier model is used to classify an input data entry as being in the MAT class.

The techniques herein are directed generally to a “zero-knowledge” data management network. Users are able to share verifiable proof of data and / or identity information, and businesses are able to request, consume, and act on the data—all without a data storage server or those businesses ever seeing or having access to the raw sensitive information (where server-stored data is viewable only by the intended recipients, which may even be selected after storage). In one embodiment, source data is encrypted with a source encryption key (e.g., source public key), with a rekeying key being an encrypting combination of a source decryption key (e.g., source private key) and a recipient's public key. Without being able to decrypt the data, the storage server can use the rekeying key to re-encrypt the source data with the recipient's public key, to then be decrypted only by the corresponding recipient using its private key, accordingly.

An artificial-intelligence-based decision-assisting system and method are disclosed for generating ranked recommendations through adaptive multi-source analysis. The system includes a processor and a non-transitory computer-readable storage medium storing executable instructions that implement a scoring engine and a ranking engine. Decision parameters and user-defined weighting factors are received from user devices and combined with system-defined weighting factors retrieved from behavioral, historical, external-context, and scoring-criteria databases. Composite decision scores are computed and used to rank candidate options.

Results are displayed via a graphical user interface, and anonymization procedures protect user identity. The method supports concurrent processing and adaptive learning to refine decision predictions.

User credibility scores derive from attributes including timeliness, integrity, and completion, with dynamic normalization that decays older transactions while emphasizing recent verified activity. Scores appear as letter grades or quantitative indicators, with separate buyer and seller indices. Credibility indicators are distributed through web and mobile applications, APIs, and unique public-profile links, allowing verified reputation to follow the user across platforms.
