A computer system and associated methods for verifying user identities online. Identity claims made by a requestor of an online access and/or a trusted transaction may be verified by associating digital credentials to verified personal identification information (PII) retrieved from real world events. PII item(s) may be retrieved from third-party verified identity information sources. Verified personal attributes related to PII items may be identified and correlated with the requestor's digital credentials, and stored to a verified identity record. Additional digital credentials for the same requestor may be similarly identified, correlated, and stored to the verified identity record. A subsequent transaction request by a person claiming the requestor's identity may be compared with the verified identity record. An identity match indicator and/or a match confidence score may be created and used to determine the risk that the identity claim by the person requesting the transaction is false.

Time-varying scent determined by audio-meaningful events, such as gun firing, in an audio signal is generated by first computing a spectrogram thereof. A fingerprint, each having feature points, can be extracted from the spectrogram over a time window. The plurality of feature points is hashed to give a hash code. A sequence of hash codes obtained over multiple time windows is correlated with predetermined hash-code segments of known audio-meaningful events stored in a database. A matched audio-meaningful event having a highest correlation is identified. The scent-generating recipe corresponding to the matched audio-meaningful event is retrieved. Atomizers are used to vaporize scent-generating substances to generate the time-variant scent. Since the hash code has a fixed length and a smaller size than the plurality of feature points, storage requirements of the database and computation requirements of correlation calculation are reduced by using the hash code rather than the plurality of feature points.
