Now that the search is completed and Hotel Search Agent presents user with list of hotel, the customer would go about booking the hotel of his choice as shown in Fig. 3. On completion of displaying the search result, the guest is allowed to select a hotel of choice for booking from the listing in Fig. below. As illustrated, the Guest is about to book hotel highlighted Wyndam, Kingston, Jamaica from the result listing shown in Fig. 3. Each hotel desired for booking is checked for verification with VeriSign before continuation of the booking process. This means their existence is validated based on third party certificates obtained from the third party, which in our case is VeriSign as shown in Fig. 4. The logo depicted in Fig. below indicates the trusted third party logo that we are using in SAL-HSB. When the user continues by clicking on “Book Now” security checks are made after which if successful, user will be allowed to continue with the booking process. The security agent connects over HTTPS using third party APIs to check if certificates used by booking agent are authentic and still valid. Only then are users allowed to book the hotel.
