Thus the smart door lock can meet application requirements of different scenarios, especially when users forget to carry keys or forget passwords.
In order to more clearly explain technical solutions in the embodiments of the present disclosure or the prior art, drawings that need to be used in the embodiments or the prior art will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present disclosure. For those ordinarily skilled in the field, other drawings can be obtained without paying creative work.
In order to make purpose, technical solution and advantages of the embodiments of the present disclosure more clear, the following is a clear and complete description of the technical solution of the embodiments of the present disclosure, with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only some but not exclusive embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those ordinarily skilled in the field without creative work should fall within the scope of protection of the present disclosure.
Unless otherwise indicated, technical or scientific terms used herein shall be interpreted as generally acknowledged by those ordinarily skilled in the field to which the present disclosure belongs. Terms of “first”, “second”, “third” and “fourth” and the like used in the present disclosure are used to distinguish different objects instead of sequencing a specific order, quantity or importance. Similarly, terms such as “a”, “one” or “the” do not intend to limit quantity, but merely to state the presence of at least one. Similar terms such as “including” or “comprising” mean that the elements or articles appearing before the terms cover the elements or articles and their equivalents listed after the word, and do not exclude other elements or articles. Similar terms such as “connected” or “communicated” are not limited to direct physical or mechanical connection, but also include direct or indirect electrical connection. Terms such as “up”, “down”, “left” and “right” are only intended to indicate relative position. When an absolute position of a described object changes, the relative position may also change accordingly.
Embodiment herein refers to that particular features, structures, or characteristics described therein may be included in at least one embodiment of the present disclosure. The word cited in different sections of the specification does not necessarily refer to be understood as in the same embodiment, nor refer to an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the field understand explicitly and implicitly that the embodiments described herein may be combined with other embodiments.
To help those skilled in the field better understand the present disclosure, some terms will be explained below.
1) A user equipment (UE) is a device that provides voice and/or data connectivity to users, such as a handheld device, a vehicle-mounted device or the like with a wireless connection function. Common user equipments include, for example, mobile phones, tablet computers, notebook computers, handheld computers, mobile internet devices (MID), wearable devices such as smart watches, smart bracelets, pedometers or the like.
2) A fingerprint identification module is configured to identify individual fingerprint features through a specific induction module. For now, the fingerprint identification module mainly includes an optical fingerprint identification module, a capacitive fingerprint identification module and a radio frequency fingerprint identification module. The physical structure of the fingerprint identification module may be a fingerprint chip in chip package.
3) Fingerprint information refers to image data of a person's fingerprints stored in a certain way so as to be browsed, consulted or compared and analyzed when necessary. Fingerprint information includes fingerprint features, which represent fingerprint feature points of fingerprint images. Fingerprint features include overall features and local features, where overall features include basic grain patterns of loop, arch and whorl. Local features refer to minutia points of fingerprints. Two fingerprints may generally have an identical overall characteristic, but their local characteristics—minutia points—cannot be exactly the same. Fingerprint lines of minutia points are not continuous, smooth or straight, but generally break, bifurcated and curved. These breakpoints, bifurcation points and turning points are called “minutia points”. These minutia points provide unique verification information for fingerprint. Minutia points on fingerprints have five different characteristics: 1. endings, where each fingerprint line ends; 2. bifurcations, where each fingerprint line is bifurcated into two or more lines; 3. ridge divergences, where two parallel fingerprint lines are diverged; 4. dots or islands, which are very short fingerprint lines, which may also be deemed as dots; 5. enclosures: where each fingerprint line is bifurcated for a short distance and then merged into one, forming a small ring called enclosure. Fingerprint features data may also include: short ridges: which are short fingerprint lines but not short enough to be a dot; orientations: where minutia points are directed; curvatures—which describes a direction changing rate of fingerprint lines; positions: which may be described by (x,y) coordinates, and may be absolute identification or inductive identification relative to triangular points or feature points.
4) Matching means that some or all features of compared objects are the same. For example, if some features of fingerprint information are the same as those of a pre-stored fingerprint template, or if all features of fingerprint information are the same as those of the pre-stored fingerprint template, then the fingerprint information is matched with the pre-stored fingerprint template, otherwise, it is not matched.
5) “Multiple” refers to two or more than two. “And/or” describes an association relationship of associated objects, indicating that there can be three kinds of relationships, for example, A and/or B, which can indicate that there are three cases of A, A and B, and B alone. The character “/” generally indicates that the context object is an “or” relationship.
Embodiments of the present application will be described below with reference to the accompanying drawings.
