The voiceprint features are then compared. And determining the similarity of the first voice and the current voice information by comparing the similarity of the voiceprint characteristics. The comparison of the voiceprint features can be realized by acquiring the images of the voiceprint features, comparing the difference of the two images, or by other means.
After a plurality of first target account numbers are determined, the first target account numbers can be displayed to the current object or prompted to the current object. And selecting a second target account from the plurality of first target accounts by the current object. After the second target account number is selected, the second target account number corresponds to voice information. At this time, a second voice of the first object is acquired, and the second voice is compared with the voice information of the second target account, so that whether the current object is the object corresponding to the second target account is determined. And under the condition that the similarity between the second voice and the voice information of the second target account is greater than a first threshold value, determining that the current object is an object corresponding to the second target account. At this time, the recording apparatus is logged in using the second target account. If the recording equipment logs in other account numbers before logging in, the recording equipment automatically logs out other account numbers and then automatically logs in a second target account number.
