In one embodiment, a trusted cloud service such as an “electronic vault” may store records of a consumer's electronic data file history. These documents may come from disparate providers and include financial statements and the like. The trusted vault cloud may act as an online notary to certify documents are legitimate and may be trusted. For example, a retailer may dispute whether the consumer paid a debt. To resolve the issue the retailer may access the cloud vault to retrieve a bank statement for the consumer, whereby the bank statement is electronically notarized by the vault cloud and is thus credible to the retailer. The retailer may then see proof the consumer had indeed paid a past debt to the retailer. Other embodiments are described herein.
