VIVAnews -enter the school holidays at the end of June to mid July 2011, police increased security in a number of tourist locations. According to the Director of Security Vital Polda Metro Jaya Object Commissioner Suntana, it've prepared tourist police personnel for patrols in some locations.

"The placement of personnel on location tours especially on the holiday season is already a regular schedule," he said.

Suntana explains, in the conduct of security, the police cooperate with internal security officers. "We make sure that some of the locations that became a tourist destination has been maintained," he added. It is intended to ensure the security of the visitor location jaunt. The location that became the focus of security, among others, Ancol, Taman Mini Indonesia Indah, Ragunan Zoo as well as a national monument.

Head of public relations Polda Metro Jaya Commissioner Baharudin Djafar said, safety of tourist locations are indeed already entered in the annual calendar Kamtibmas. So, he continued, these safeguards is indeed already a routine operation. "It is already included in routine operation, and placement of personnel is focused on location tours," he added.

Baharudin reveal, aside from location, officers also secured the line to tourist spots. "We also coordinate with the Police, such as West Java and Banten to security lines," he asserted.

According to him, there are some lines that will be populated mostly by the Jagorawi toll road like vacation, Tangerang Toll and the toll In the city towards the North Jakarta. Baharudin hope, in the holiday season this time do not occur something disturbing security.

The Holiday Season, Police Tighten Security

As with the computer virus, spyware can be broken down into a number of different categories. Most users are familiar with the term "adware" which refers to software which serves annoying ads. There are however a number of other spyware variants you should be aware of.

To begin with it is important to have a clear definition of spyware. This will also help us understand why the term is commonly used to encompass a number of different variants. Spyware is a program, usually installed without your knowledge, which records what you do on your computer and then shares it with its creator.

The information which the spyware program collects can vary from the websites you visit to log-in and passwords for your online banking site. The sharing of your personal information with a third party is why spyware in its purest form is labelled as a malicious threat and clearly is a major privacy issue.

Adware is the second mostly commonly used term. Adware is designed to display adverts relevant you, commonly based on your surfing habits, to generate Pay-Per-Click advertising revenue or sales through affiliate links. Adware is commonly bundled with free software by developers instead of charging a price.

The malicious nature of adware can vary enormously. At one of the scale, adverts are displayed in a non-intrusive manner in a window within the free program you have downloaded. When the program is not running, ads are not displayed. At the other end of the scale, a user could find their desktop overwhelmed as the adware program spews out multiple pop up ads in a very aggressive manner. Whilst it may be possible to believe the former is not transmitting personal data to a third party, it is difficult to expect the later not to.

The adware issue is further complicated by marketing companies who do not like their software being labelled "spyware." These marketing companies generate millions of dollars of income often via recognised brand name clients. So to avoid legal issue security companies refer to this software as PUPs (potentially unwanted programs).

Browser hijackers are another aggressive form of spyware. They attack important browser settings like your default homepage which your browser loads when you start the program. Hackers direct you to sites which generate revenue for them like the Russian website "Cool Web Search". Browser hijackers can also insert sites into your bookmarks. They also can cause your browser to crash and stop working completely and are typically difficult to remove.

Key Loggers capture all your key strokes into a DLL file which the creator retrieves. Software key loggers are often bundled with a Trojan Virus which gives the creator access to your computer.

Here are some tips and strategies to fight the different types of spyware.
- Keep Windows XP and ALL your web browsers (including Internet Explorer and FireFox) up to date with the latest patches.
- Install a reputable anti-spyware program like Webroot Spy Sweeper or PC Tools Spyware Doctor. Run frequent scans and keep the definitions up to date.
- Install a reputable anti-virus program like Norton Anti-Virus or McAfee VirusScan. Run frequent scans and keep the definitions up to date.
- Install a firewall which manages both inbound and outbound connections. Top personal firewall software picks include Zone Labs's Zone Alarm and Norton Personal Firewall. Alternatively purchase a router with a hardware firewall.
- Avoid downloading free software programs including screensavers and weather toolbars.
- Avoid know high spyware risk area on the internet including illegal music sharing sites, Peer-to-Peer programs, free game download sites and adult sites.

Update for latest 2010 USB disk security

This safety-lock circuit use the new Atmel AVR microcontroller series, the ATtiny26. This micros (and new ATmega8, ATmega16 etc) are powerful microcontrollers with new features like

• internal RC calibrated oscillator for 1,2,4 and 8 MHz speed (working with external RC up to 16 MHz too)
• Analog to digital converter 10-bit (10 channels)
• Very high speed In System Programming (compare it with AT90Sxxxx series)
• internal Brown-out detector

and much more...
Circuit description
This circuit its not write any data to the telecard. The ATtiny26 read the 16 first bytes of telecard and then store them to internal eeprom of ATtiny26.

When you insert any telecard to the slot (telecard`s base) it will pressed the switch SW1. The ATtiny it will understand that new card insert in the slot and go to read it. Temporary will save the 16 first bytes of the card to the RAM and after the ATtiny will search in internal eeprom to see if this telecard is registered to the system. if not, it will turn-on the Red LED. The ATtiny have 8 groups of 16 bytes each, summary 8*16=128 bytes of eeprom memory.
The ATtiny of this circuit its working with internal RC oscillator at 1MHz, that is the default setting from the factory.
1. Register a telecard to the system:
With any telecard in to the slot, press the SW2 to register the card to the system. The ATtiny will search the internal eeprom for empty memory group (1 group=16 bytes with $0F values). If there is empty group, it will read the 16 bytes from RAM and store them to the eeprom. Then, the ATtiny will reboot, reset the telecard, read it again and check if the card is registered (by compare the 16 bytes of telecard, with 1 group at the time, with internal eeprom).
Now it will turn-off the Red LED and turn-on the green LED because we have register this telecard to the system. At the same time it will arm the relay connected to PB6 pin via BC547.
The internal eeprom of ATtiny26 is 128 bytes. So, we can register up to 8 telecards (keys) to this memory. (8 telecards)*(16 bytes for each telecard)=128 bytes of internal eeprom
2. Unregister an registered telecard from the system:
If for some reason we don't want to use any of 8 registered telecard, we can unregister it from the system. We have to insert this card to the slot, the ATtiny accept it (by turn-on the green led). If we press the SW3, the ATtiny will search to internal eeprom to find were the 16 bytes are stored and delete them by write the value $0F to this memory group. Now the ATtiny will reboot, read again the telecard, compare the first 16 bytes of the card with the internal eeprom and because we have unregister this card it will turn-on the red LED. This telecard is unregistered now. We can register the card again if we want to, by follow the step 1.
3. Erase entire internal eeprom of ATtiny26:
If we have register 8 telecards to the system and will try to register 1 more (9th), when we press SW2 to register the card, the ATtiny it will flash the Red and Green LEDs 4 times alternately. The only way to register some other telecard, is to unregister some one of 8 registered cards (step 2.) or to erase entire eeprom (writing the value $0F to all locations). To erase entire eeprom (128 bytes 0-127) we have to press the SW3 button with NOT any card inside to the slot, for 2 seconds, to ensure the ATtiny that we are not press the button SW3 by asccident . At this case the ATtiny it will flash the Red LED 4 times. After that, the internal eeprom of ATtiny it will cleared.
The values of default internal eeprom bytes are $FF. If we insert the telecard with wrong pins position (reversely), the ATtiny will read 16 bytes with $FF values because of internal pullup resistor of PB4. If we let the eeprom to default value ($FF), when we insert any card (anything with telecards dimensions) just to press the switch SW1, the ATtiny will read 16 bytes with $FF value (because internal pullup resistor of PB4) and will arm the relay. By set the eeprom to $0F value, at the phase of programming the safety_lock.eep file of ATtiny, we protect the system from this mistakes.
You can replace the $0F value of the source code with the value of your choice, for example $AB or $CF etc. Remeber to replace all the $0F values of the source code, not only the 128 bytes of eeprom. The telecard base and the main circuit are build them to different boards for more commodity.

If you can not find the ATtiny26 in the markets, you can use the AT90S2313 that is most ordinary. For that i made a new version of safety-lock for AT90s2313 microcontroller. The characteristics of the safety-lock are the same with ATtiny26 version (erase-register-unregister card-, functions). The only change is the different pins-ports connections between telecard and microcontroller and the addition of 4 MHz crystal, because the ATtiny26 works with the internal RC oscillator at 1 MHz.

Electronic safety-lock with telecard as key

This simple circuit is the electronic version of the combination lock. Using the special purpose LS7220 digital lock IC, the circuit allows a 4 digit combination of your choice to activate a relay for a set period of time. This relay can then be used to trigger a lock solenoid, enable a starter button, open a motorized door, or many other tasks that require a momentary signal.

HD1	1	12 Position Header

Notes
To set the combination, wire the appropriate switches to U1 pins 3, 4, 5 and 6 using the header. For example if S1 was connected to pin 3, S2 to pin 4, S3 to pin 5 and S4 to pin 6, the combination would be 1,2,3,4. Now wire all other unused switches across the header to pin 2 of U1. In this way you can create any 4 digit combination you want. Pin 2 is the reset pin, so connecting all unused keys to it assures that the entire combination must be reentered if an incorrect key is pressed.
When the appropriate combination is entered, the relay is activated for a period of time determined by C1. The 1uF capacitor specified in the parts list will result in an on-time of roughly 5 seconds. Increase the value of C1 to increase this time.
An easy way to make a keypad is to buy 12 PC board mount pushbuttons and then etch a PC board so that the buttons are in 4 rows of 3, similar to a telephone keypad. Place this in a case and then use a label maker or transfer letters to add your numbers to the tops of the pushbuttons. You can also use a pre made keypad but keep in mind that you need a pad which provides an output for each key. Most pads available have the keys connected to provide a row and column signal when they are pressed.
