Abstract
In order to avail of some service, a user may need to share with a service provider her personal chronological information, e.g., identity, financial record, health information and so on. In the context of financial organisations, a process often referred to as the know your customer (KYC) is carried out by financial organisations to collect information about their customers. Sharing this information with multiple service providers duplicates the data making it difficult to keep it up-to-date as well as verify. Furthermore, the user has limited to no control over the, mostly sensitive, data that is released to such organisations. In this preliminary work, we propose an efficient framework – Verifiable Information Graph or VIGraph – based on generalised hash trees, which can be used for verification of data with selective release of sensitive information. Throughout the paper, we use personal profile information as the running example to which our proposed framework is applied.
