Background
Along with the popularization of science and technology and the development of smart homes, more and more people also begin to select the smart door lock.
At present, along with the development of biometric identification technology, the technology of applying biometric identification technologies such as fingerprints and irises to intelligent door locks is more and more mature. However, since the computer processes the biometric features (e.g., fingerprint, iris), only limited information about the biometric features is involved, and the comparison algorithm is not an exact match, the result cannot be guaranteed to be 100% accurate. An important measure for a particular application of biometric systems is the recognition rate. Mainly consists of two parts, the rejection rate (FRR) and the false rate (FAR). We can adjust these two values for different purposes. FRR and FAR are inversely proportional.
The intelligent door lock utilizing the biometric identification system is related to personal and property safety of a user, so that the misjudgment rate is set to be very low, and the rejection rate is higher. Due to individual difference or environmental influence, the biological characteristics are not obvious or attachments such as water, dust and the like easily occur, so that the rejection rate is greatly increased, and the user experience is influenced.

The examples merely typify possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in or substituted for those of others. The scope of embodiments of the invention encompasses the full ambit of the claims, and all available equivalents of the claims. Embodiments may be referred to herein, individually or collectively, by the term "invention" merely for convenience and without intending to voluntarily limit the scope of this application to any single invention or inventive concept if more than one is in fact disclosed. Herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed. The embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. For the structures, products and the like disclosed by the embodiments, the description is relatively simple because the structures, the products and the like correspond to the parts disclosed by the embodiments, and the relevant parts can be just described by referring to the method part.
The intelligent door lock combines a biological characteristic identification system, such as a fingerprint identification system, an iris identification system and the like, a fingerprint lock, an iris lock and the like are generated, the safety is high, and the loss and the damage do not exist. However, when incorporating biometric recognition systems into smart door locks, a conflict between the rejection rate and the user experience arises. The rejection rate is high, the safety is good, but the user is easily rejected, and the intelligent door lock cannot be smoothly opened, so that the user experience is poor. On the contrary, the user experience is improved, but the safety is easily reduced. Therefore, as shown in fig. 1, illustrating a first aspect of the embodiments of the present invention, there is provided an identity authentication success rate improving method applied to an intelligent door lock, including,
And step 120, adjusting and reducing the preset rejection rate. The preset rejection rate is preset in the intelligent door lock, and the preset rejection rate is relatively high on the premise of safety, such as 99.99%. The reduction range of the preset rejection rate can be set differently according to different users, and can also be set as a value in a unified manner. For example, for the elderly or children, the biological characteristics, especially the fingerprint characteristics, are not so obvious and are greatly influenced by the environment, and the set reduction range can be appropriately large, for example, reduced to 95%. For users of teenagers, middle-aged people and the like in other age groups, the change of the biological characteristics (fingerprints, irises and the like) is not large, and the set reduction range can be smaller, such as reduced to 98%. The specific setting is only needed.
According to the method for improving the success rate of the identity recognition, after the intelligent door lock receives the identity information of the user, the fact that the user enters the unit door can be determined, at the moment, the preset rejection rate of the intelligent door lock is adjusted and reduced, the user can conveniently conduct identity verification by using biological characteristics such as fingerprints and irises, the intelligent door lock can be conveniently opened, and the usability of the intelligent door lock is improved. That is, when the smart door lock does not receive the user identity information (i.e., the user does not go home), the rejection rate is a preset rejection rate, and the preset rejection rate has a high value, on the premise of safety. Therefore, in the embodiment of the invention, by the combined gate machine (such as a unit gate machine), the judgment rejection rate of the intelligent door lock is dynamically adjusted and reduced in the period that the user needs to open the intelligent door lock at home, the contradiction between the usability and the safety of the intelligent door lock using the biological recognition system is effectively solved, the safety is ensured, the usability is high, and the unlocking experience of the user is improved.
