| Landlords
beware: disclosing to tenant's employer
details of rental dispute may be wrongful DPP3 |
4/04 |

The
Complaint
A tenancy dispute
over rental payment arose. In the course of taking action for recovery
of rent, the landlord's solicitors issued a demand
letter to the tenant and had it copied to his employer disclosing
details of the dispute
and the rent in arrears.
Outcome
of Investigation
Personal data
of the tenant relating to the tenancy dispute
are considered to be collected for the purpose of dealing
with or resolving the dispute between the parties. The
employer of the tenant had no prior involvement in the
tenancy nor the dispute. The landlord failed to justify why
it was necessary to write to the employer about the
dispute. The landlord might wish to put pressure on the
tenant to submit to their demand but such use of the
data was considered not within the original collection
purpose. In the absence of evidence showing that the
tenant had given his "prescribed consent¡"
to the
disclosure of his personal data in relation to the tenancy
dispute to his employer, the landlord was found in
contravention of DPP3. Enforcement notice was issued
requiring the landlord (which is in the real estate business)
to cease such practice of informing tenants' employers
in similar situations.

| Internet
security: randomly assigned instead of fixed reset password preferred
when reactivating a lockout account DPP3 |
5/04 |
|
The
Complaint
A mobile phone
service company provided an internet billing service to its customers
through its website. The electronic bills, which contained customers'
data including calling records, were password protected. In addition,
a mechanism to deactivate internet access to an account after five
unsuccessful logins was built in to preclude hacking. However, upon
reactivation of the lockout account by request of the customer,
the password would be automatically reset to a fixed number (e.g.
123456), which was applicable to all customers. This allowed a hacker
to gain access to the account information by first deactivating
an account with five unsuccessful login attempts to prompt
the customer to make a lockout report to the mobile phone
company and then logging in to the account with the fixed
reset password before the customer ever changed the
password. A complaint on the security pitfall on password
control was lodged with the PCPD by a customer.
Outcome
of Investigation
DPP4 requires
the phone company to take all reasonably
practicable steps to guard against unauthorized access
to its customers' data. Taking into account the sensitivity
of an individual's calling records, the phone company's
unvaried practice of resetting the password of a lockout
account to a fixed number was considered insufficient to
protect customers' data against possible intrusion
as
suggested above, despite the phone company's effort
to
remind customers via their system to change passwords
periodically. There was nothing suggesting that it was not
reasonably practicable for the phone company to allot a
varied, rather than a fixed, password to customer when
reactivating a lockout account. Eventually, the mobile
service provider improved its system to have the
password reset to a random number and the customer
informed of the reset password via short message sent
to his mobile telephone.

| Internet
security: system loopholes mended to prevent
unauthorized or accidental access to password protected personal
data of customers DPP4 |
6/04 |
|
The
Complaint
Another case of
internet billing service provided to
customers by a mobile phone service company. The
system was secured by password feature where a
customer had to enter his password to gain access to
his account information. In an attempt to access the
account information via the service, a customer was
alarmed to find out that it was possible to return to the
same secured pages which he had previously visited by
simply striking the "Back¡" button or via
the "History¡"
function of the browser, even after he had logged out
from the system and gone offline.
Outcome
of Investigation
By allowing such
security loopholes, the company exposed its customers'
personal data to the risk of being accessed by unintended or unauthorized
third parties, particularly so when the customers used computer
terminals available in public places. This was considered a contravention
of DPP4 in failing to provide sufficient safeguards to protect customer
data held. In response to the PCPD's findings and in
order to remedy the situations, the company immediately carried
out rectifications to eliminate the loopholes and added security
alert statements on the website, advising customers to log out from
the system and close the browser window after finished viewing the
password controlled personal information on the website.

| Personal
data collected through outdoor marketing campaigns :
organizers to take safety steps to prevent accidental loss of
application data collected DPP4 |
7/04 |
|
The
Complaint
A
bank conducted a marketing campaign in a bookshop to solicit credit
card applications on a Saturday. At the end of the campaign, the
bank staff put all the application forms together with applicants'
identity card copies in a briefcase and carried them home before
returning to office the next working day. Unfortunately, the bank
staff left the briefcase in a public light bus and lost all the
documents.
Outcome
of Investigation
Upon investigation
of the complaint, it was discovered that
the bank did not have adequate guidelines issued and given
to staff in relation to handling of personal data collected
during outside-office marketing campaigns. Taking into
account the sensitivity of the data collected and the harm
that is likely to be inflicted upon the data subject on accidental
loss of the data, the bank was found in breach of the
requirements of DPP4 in failing to take practicable steps to
protect the security of the personal data collected.
Enforcement notice was issued, and in compliance therewith
the bank implemented corresponding safeguard measures,
including the transmission of those credit card applications
and supporting documents to a nearby branch of the bank
at the end of the marketing campaign instead of allowing
staff to bring them home.
