Some embodiments of the present specification relate to an apparatus for preventing the manipulation of exercise data, the apparatus comprising: a sensor installed in a driving unit of an exercise equipment or at a position close to the driving unit, to sense vibration associated with the exercise of a user; a storage unit for recording and storing a reference value for determining whether exercise data has been manipulated, according to an operational feature of the exercise equipment; an exercise data determining unit for determining whether the exercise data of the user has been manipulated, by comparing a vibration measurement value of the exercise equipment measured by the sensor with the reference value when driving of the exercise equipment is identified; and a control unit for performing control to receive exercise equipment information from which the user may determine a unique feature of the exercise equipment to which the user logs on, extract the reference value corresponding to the exercise equipment from the storage unit, receive a result of determining whether the exercise data of the user is normal, from the exercise data determining unit, store the received exercise data when it is determined that the exercise data is normal, and not store the exercise data when it is determined that the exercise data is abnormal.
