Abstract: A server with processor(s) and memory receives a transaction request from a first device to perform a transaction with an account and determines a security level for the transaction. When the security level satisfies predetermined criterion, the server: instructs the first device to suspend the transaction and to display a first interface indicating the suspended transaction; and sends a confirmation request, to a second device associated with the account, for voice verification of the transaction. The server receives voice verification information from the second device that includes audio data provided by a user of the second device and determines whether the voice verification information matches stored account verification data corresponding to the account. When there is a match, the server: processes the transaction; and instructs the first device to complete the transaction and to replace display of the first interface with a second interface indicating the completed transaction.

Abstract: A technique for managing usage metrics of quota trees in a file system includes storing, in an inode table that lists inodes of the file system, identifiers (IDs) of quota trees to which the inodes belong. To check the usage of a quota tree, the inode table is scanned for any inodes that reference the quota tree ID of that quota tree. All such inodes are identified, and their usage attributes are summed to calculate an overall usage metric for the quota tree as a whole. The improved technique thus avoids the need to scan directory structures on disk.

Abstract: A method, apparatus, and system are disclosed for processing transactions in the field of Internet communication.

Abstract: An online tree quota check tool computes quota usage of files in a directory tree while the structure of the directory tree keeps changing due to concurrent write access by other applications and clients. The quota check tool computes the quota usage without interfering with the ongoing file access operations that change the directory content and quota usage. A quota check database keeps track of which files have been checked and which have not, so that each file is checked and its quota usage is accumulated once and only once while directories are moved and directory scans are restarted as a result of the changing directory content. File system operations are modified to synchronize with the online tree quota check. The quota check tool can be single threaded or multi-threaded. A multi-threaded tool dispatches idle directory iteration threads to scan subdirectories in the directory tree.

Abstract: Message-wise unequal error protection is provided using codeword flipping to separate special and ordinary codewords without discarding any codewords. Special messages are encoded to ensure the codeword weight is less than a certain threshold weight. Ordinary messages are encoded to ensure the codeword weight is greater than the threshold weight. The bits of the codeword are flipped to enforce the weight criterion. Ordinary and special messages are encoded using different encodings to provide different levels of error protection. Upon receipt, codewords are separated into special and ordinary codewords for appropriate decoding. If a codeword is of indeterminate type, it is iteratively processed as both a special codeword and an ordinary codeword. The decoding result of each process is periodically checked to determine which decoding result satisfies decoding criteria.
