PROBLEM TO BE SOLVED: To provide a key management device using collation of fingerprints, capable of preventing a different tenant's key from being taken out by collating a combination of fingerprint data and a tenant number, when the fingerprint data collected during collation corresponds to plural pieces of similar fingerprint data. SOLUTION: The multi-tenant key management device having the function of taking out the key by means of the collation of the fingerprints allows the corresponding key to be taken out, when the fingerprint data collected during the collation can be identified as a piece of registered data and permits the corresponding key to be taken out by means of the combination of the fingerprint data and the tenant number, when the fingerprint data collected during the collation corresponds to the plural pieces of the registered data.
