please i am abena and i want to know about the problems associated with existing image steganography systems

The Existing system in the organization involves maintenance of phone numbers of
all the people working in any organization. Whenever the administrator want to have
the communication with his subordinates, he have to look up the corresponding
phone numbers, dial up and talk to them which is a time taking process. If the phone
number is not available he have to take the help of other people. When a person
starts to interact with the system, a bookkeeping system is used in order to know the
login time and logout time, which is a tedious process. The other process is using
punch cards to know login time and logout time. which is economically expensive.
This process include
 Taking the phone number of the people.
 Maintaining login time and logout time
 If the concerned person is not available again make a call.
All the above listed tasks currently are handled manually. And it needs maintenance of
lots of phone numbers. Due to this manual procedure, lots of errors are crawling in. In
addition to all the above, keeping track of changing the new phone numbers is a big
mundane task. Where there is certainly chance for human errors.
