Apple iOS4 can secretly record the user position of iPhone and iPad

According to foreign media reports, some programmers have discovered that since the iOS 4 operating system was launched, Apple will record the movement of all iPhones and 3G iPads through a hidden file.

At Where 2.0, researchers Alasdair Allan and Pete Warden mentioned that the geographical information of the above products has been written into the database and stored in the operating system backup and device migration files, which are all operated in the background and hidden from users. , so the user is unaware of this.

Allan points out, "A possible problem is that the file is decoded and unprotected and can be synthesized on any iOS device. Of course, when the device falls into the hands of other people, they can easily access the file and know exactly where you were. Wherever I've been in a year. Although the data itself is stored on local devices and synthetic devices, there is no evidence that it was transmitted."

Since the Apple iOS 4 operating system was released with the iPhone 4 in 2010, a question and answer page and supporting open-source applications can display hidden files and output user history coordinate data to the map.

Allen and Wharton have contacted Apple's product safety team but have not yet received a reply.

The Partial Tension Fitting is primarily used for tubular busbar and conductors, hard bus (soft bus) connected with outlet terminal and electrical equipment, conducting with high performance and contact stability.

According to the structure is divided into bus expansion joint, expansion joint, trbular busbar slot type bus bar expansion joint, copper aluminum transition plate, four second clip of variable.

Material generally using a copper aluminum copper alloy parts.
