An account abuse detection or prevention device, a data collection device, and an account abuse detection or prevention program, which are capable of promptly detecting or preventing abuse of an account.
An account abuse detection device (6) includes an access-amount-related value information receiving unit (11) and a detection unit (12). The access-amount-related value information receiving unit (11) receives access-amount-related value information from a management device (3). The management device (3) manages a specific account. The specific account is used when transmitting data from a plurality of data transmission devices (2) to a data collection device (5) via a public network. Access-amount-related value information is related to an access-amount-related value. The access-amount-related value is related to the amount of access by the public network (4) through the account. The detection unit (12) compares the access-amount-related value to a predetermined threshold value to detect abuse of the account.
