However, it also has disadvantages. Compared with the first two methods, it has a strong interference with the human body and must be fixed on certain parts of the human body. When the relative position changes, it may lead to inaccurate measurement results.
In addition, the existing methods do not take into account the situation that the faller denies that he was rescued after being rescued, and the rescuer is framed as the injured person, so it is necessary to propose a non-denial fall safety rescue plan

Embodiment 1
[0049] Embodiment 1, an effective and non-repudiation fall rescue method based on the android platform proposed by the present invention, such as figure 1 As shown, including the following seven steps:
[0050] (1) The user terminal sends the user's identity information to the server to request registration; after the server receives the registration request, it verifies the user's identity information, and if the verification is passed, it generates a user account UID for the user, which is used between the user and the server Symmetric key K for communication A and the asymmetric key used for signing (PK A ,SK A ), and sent to the user terminal, otherwise discarded;
[0051] (2) The user terminal collects the movement characteristics of the user's normal activities for a period of time through an adaptive learning process; and processes the collected user movement characteristic data to obtain the characteristic data for judging the user's fall;
[0052] (3) The user ter...
Embodiment 2
[0085] Embodiment 2. An effective and non-repudiation fall rescue system based on the android platform, including two modules: a server module and an intelligent terminal module;
[0086] Among them, the server module includes two units:
[0087] Cryptographic service unit: mainly used to generate keys for users, provide encryption and decryption and signature verification functions for related services; cryptographic service unit receives and completes cryptographic business requests sent by user request processing units, such business requests include but are not limited to user Key generation, query, cancellation and update operations, and secure storage of the generated keys;
[0088] User request processing unit: process various user requests, including but not limited to: user registration, help package archiving, rescue application, testimony and key change.
[0089] Among them, the intelligent terminal module includes five units:
[0090] Personalized setting and sel...

Abstract
The invention discloses an effective and anti-repudiation tumble helping method and system based on an android platform. The effective and anti-repudiation tumble helping method based on the android platform includes that a user uses identity information to register; a user terminal acquires tumble feature data through adaptive learning; the user terminal monitors whether the user tumbles in real time; if the user tumbles, a rescue package with signature is broadcast to the neighboring users, and help seeking information is sent to the kinsfolk; the neighboring users can help actively after receiving the help seeking information, and the neighboring users can select to turn into witnesses. The effective and anti-repudiation tumble helping method and system based on the android platform are featured with repudiation resistance, user privacy protection, reset resistance, key compromise attack resistance and the like; the effective and anti-repudiation tumble helping method and system based on the android platform are aimed to actively provide real and reliable helping evidence for an active helper and avoid false incrimination after providing help, are not limited to the old people and are capable of providing convenient and reliable health-care help for different ages of users. The effective and anti-repudiation tumble helping method and system based on the android platform are capable of detecting the human body tumble events in real time, performing the automatic intelligent help seeking and helping treatment at first time and providing anti-repudiation helping evidence for the active helper.
Description
technical field [0001] The invention relates to the mobile Internet field based on an android mobile phone system, in particular to an effective and non-repudiation fall rescue method and system based on an android platform. Background technique [0002] Under the general trend of population aging in our country, timely and efficient fall rescue for the elderly has high economic value and social significance. However, due to the adverse effects of some historical cases, there is currently a common social phenomenon in China where the elderly fall to the ground and no one dares to help them. There are endless public opinion disputes about "whether the elderly fall to help or not". The Ministry of Health has also issued relevant Technical guidelines, but these are only guidelines from the perspective of ethics and methods, and it is urgent to propose a practical fall rescue plan based on scientific and technological means. [0003] At present, there are many fall detection me...
