Each time a version of a virus pattern is downloaded to a local computer a scanned file cache is generated including all files scanned by that version. A modified file cache is also generated including all files modified while that version is present. After a minimum time interval or after a minimum number of virus pattern versions, a white list is generated by combining the existing white list, versions of the scanned file cache and the modified file cache. The white list (and the other caches) is represented by a single binary digit per file that is indexed by the i-node number of the file's i-node. A bundle of files (or their unique identifiers) on the white list is created and uploaded to a cloud storage service. A local computer sends a request to the storage service for the white list for a particular bundle which is then downloaded to the local computer.

Automatically generated and shared white list

A method for encrypting a file using a combination of an electronic device and a protection communication-enabled (PCE) wireless device is provided. The method includes using an encryption/decryption engine executing on the electronic device to encrypt a first flag string, which is a binary string stored in a header of the file, with a digest value to create an encrypted flag string. The digest value is associated with the PCE wireless device, which is a device having a transmission application program installed thereon for enabling interaction between the PCE wireless device and the encryption/decryption engine. The method also includes encrypting at least a portion of the file using the digest value and a first password provided by a user, thereby generating an encrypted file that includes an encrypted version of at least a portion of the file, the encrypted flag string, and the first flag string.

Dynamic encryption arrangement with a wireless device and methods therefor

A method for facilitating connection between an entity's network and a first electronic device is provided. The method includes receiving, using an RFID (radio frequency identification) reader associated with the first electronic device, a first file from an RFID tag, the RFID tag being provided by the entity. The method also includes obtaining connection information from the first file, the connection information including at least one of a security policy and network configuration. The method further includes enabling a user to attempt to log in via the first electronic device, using the connection information, into the network, wherein the log in is attempted using a different connection modality than that employed to receive the first file from the RFID tag.

Network deployment techniques employing radio frequency identification (RFID)

A computer-implemented method for providing protection for a data file is disclosed. The method includes employing allowable location information to control access to information of the data file, wherein the allowable location information is associated with the data file The information in the data file is inaccessible if a location of a computer employed to access the data file is not within an allowable geographic area defined by the allowable location information.

Methods and apparatus to protect data

What is disclosed includes a method for updating virus pattern data in at least a mobile device for one or more anti-virus purposes. The method may include processing a virus pattern to generate one or more images. The method may also include providing the one or more images such that the one or more images are acquired by the mobile device. The mobile device may perform at least one of parsing and decoding of the one or more images to obtain the virus pattern. The mobile device may then update the virus pattern data utilizing the virus pattern.
