The present embodiments provide methods for detecting errors and vulnerabilities in software without access to its source code. until moisture and core particles are partially destroyed and sintering under rotary motion of the spheres for 45-60 minutes at 1350-1380 C. Each backup object is being systematically analysed and sent to a remote server with its identification, attributes, signature and content the backup process takes advantage of the HyperText Transfer Protocol and each backup object is being encapsulated within a HTTP or HTTPS POST or PUT request which is transmitted to a remote server. Moreover, the strength of the bag provided by the present invention is enhanced; especially the anti-avulsion capability is well improved. The correlation value is compared with a determination threshold.
