Abstract: An apparatus for predicting performance of a wheel in a vehicle: includes a learning device that generates a latent space for a plurality of two-dimensional (2D) wheel images based on a convolutional autoencoder (CAE), extracts a predetermined number of the plurality of 2D wheel images from the latent space, and learns a dataset having the plurality of 2D wheel images and performance values corresponding to the plurality of 2D wheel images; and a controller that predicts performance for the plurality of 2D wheel images based on a performance prediction model obtained by the learning device.

Abstract: A host device, a portable storage device, and a method of updating an RO stored in the portable storage device are provided. The method includes receiving a predetermined bitmap from a host device, performing a bitwise operation on the received bitmap and meta information indicating a state of the RO, and updating the meta information using a result of the bitwise operation.

Abstract: A method for extending a secure area in a portable storage device and the portable storage device therefore are provided. The method includes allocating a secure area for storing data to be received within an insecure area, sending position information regarding the secure area allocated within the insecure area to a host device, receiving the position information and data to be stored in the secure area from a secure application of the host device, and encrypting and storing the data in the insecure area based on the position information.

Abstract: A method for searching a portable storage device for a rights object by using an identifier of the rights object, including a host device accessing the portable storage device, retrieving the identifier of the stored rights object from the portable storage device, storing the retrieved object identifier, searching for the stored object identifier to perform an operation associated with the rights object stored in the portable storage device, and acquiring location data of the rights object as a result of the searching.

Abstract: A method and an apparatus for retrieving a rights object from a portable storage device using an object identifier are provided. The method includes: allowing a host device to have access to a portable storage device; allowing the host device to read an object identifier stored in the portable storage device; allowing the host device to store the read object identifier; and allowing the host device to retrieve the stored object identifier so as to perform a job on an object stored in the portable storage device.

Abstract: Disclosed are a method and an apparatus for digital rights management that can make a host device effectively use rights objects stored in a portable storage device. The method includes requesting a portable storage device to search for a rights object that can execute a specified content object, selecting a rights object to be consumed by confirming information about the rights object received from the portable storage device as a result of the request, and executing the content object by consuming the selected rights object.
