    摘要: A method, program and apparatus for providing access to alternate images in an electronic document are provided. The present invention comprises identifying an initial image to be displayed in an electronic document (typically a web page) and then determining if alternate versions of the image are available for display. If alternate versions of the image are available, they are provided within the same electronic document. The alternate images differ from the initial image in size and resolution, allowing users with visual impairments to access larger, higher resolution images. The user accesses the alternate images by means of a selector displayed within the electronic document. When selected, the alternate image replaces the initial image in the electronic document, and the document is reformatted.

    摘要: A system and method for using write-and-destroy transaction cards which cannot be reprogrammed. The write-and-destroy transaction cards are programmed (i.e., written to) at bit increments representing, in total, the stated value of the card. The stated value may be represented in one or a plurality of denominations and currencies. In use, the remaining value of a card can be ascertained at a merchant location by reading those bits which have not been erased. The remaining value can additionally be confirmed by contacting the issuing financial institution using a unique serial number which may be encoded onto each transaction card. Upon confirmation that the card has sufficient value to conduct the desired transaction, the card is decremented by erasure of the bits representing that value. By invocation of locally stored software, or based upon communication with a host location, the current rate of currency exchange between the merchant-preferred currency and the currency represented at bit increments on the transaction card can be ascertained and the appropriate value decremented by erasure from the card. Once bits have been erased, they cannot be reprogrammed.

    摘要: A method and apparatus for obtaining user information to conduct secure transactions on the Internet without having to re-enter the information multiple times is described. The method and apparatus can also provide a technique by which secured access to the data can be achieved over the Internet. A passport containing user defined information at various security levels is stored in a secure server apparatus, or passport agent, connected to computer network. A user process instructs the passport agent to release all or portions of the passport to a recipient node and forwards a key to the recipient node to unlock the passport information.
