An integrated mobile personal electronic device for securely communicating, managing and updating user's work related tasks and in parallel supporting the user's private life daily operations, comprising: a mobile communication device equipped with a cellular modem to enable data communication over cellular and internet networks, said mobile communication device configured to receive and send both the user's employer enterprise work related data as well private data with a plurality of sources; characterized by said integrated mobile personal electronic device comprising an electronic sleeve configured to be attachable to said mobile communication device to create together with said communication device a unified single device, said sleeve comprising at least a CPU, a solid state large capacity secured memory module equipped to seperately store and manage said user's work and personal data, a RAM unit and an at least one biometric sensors module; wherein; said biometric sensors module comprises at least one biometric measuring parameter sensor, each of said at least one sensors measuring and generating a different biometric parameter; wherein said electronic sleeve contains a software module that activates a set of functions for enabling secured access and communication between said sleeve with a plurality of operational functions of said user work related tasks residing at said user remote employer enterprise IT resources; said sleeve storing secured enterprise work related data and said sleeve storing registration biometric data uniquely associated with the unique legitimate user, wherein in response to said biometric sensors module measured and sampled signal sequence, followed by said sleeve CPU receiving positive authentication of the unique legitimate user, said electronic sleeve activates and creates direct two-way secured data communication channel through said communication device cellular modem between said user and said user remote work enterprise IT resources, and wherein said at least one of biometric sensors continuously reads and analyzes a plurality of personal biological identification parameters with the person holding the integrated personal electronic device, said identification parameters associated with registered user and in the event that a noticeable change occurs in any of said measured personal biological identification parameters, access to the enterprise's data files stored in the sleeve is denied and the operation of said electronic sleeve device is completely shut down while the operation of said mobile communication device remains functional. a mobile communication device equipped with a cellular modem to enable data communication over cellular and internet networks, said mobile communication device configured to receive and send both the user's employer enterprise work related data as well private data with a plurality of sources;
