According to aspects of the inventive concepts, provided is a method for erasing information based on a dual-security mechanism. A storage medium feature database, an information erasure feature database, and a firmware system feature database are built to match cases for to-be-erased electronic scrap. An erasure solution and a native system data package are generated based on the matching results. The information is erased and an erasure result is evaluated; and the information is recovered on the erased electronic scrap, and a recovery result is evaluated, to implement comprehensive double security evaluation. The information erasure validity of the electronic scrap is checked based on the evaluation results. If an erasure result is invalid, erasure solutions are corrected online based on the evaluation result, until the erasure result is valid and the electronic scrap with a native system recovered is obtained.

Methods and apparatuses () for detecting body-related temperature changes are provided. The method comprises measuring a skin-surface temperature at a first temperature sensor element () at a measuring rate (S) and measuring an ambient temperature at a second temperature sensor element () at the measuring rate (S). The method also comprises calculating a plurality of first change rates for the skin-surface temperature and a plurality of second change rates for the ambient temperature over a time interval (S). The method further comprises determining, based on the plurality of first change rates and the plurality of second change rates, whether an ambient temperature change rate is faster than a skin-surface temperature change rate by a threshold (S). The method additionally comprises selecting whether or not to trigger an alarm based on a result of the determining (S). With the methods and apparatuses (), the number of false alarms may be significantly reduced.
