Solution 3:

The word avoid pretty much sums it up as well as possible. If you were to run into your "friend", they may ask, "Hey, are you avoiding me?". You could also use dodge, although this feels a little more dynamic. It might be better suited for when you see your friend coming, and you slip into an alley to avoid being seen. You could also use duck in the same manner as dodge. Avoid would be the better choice for premeditated evasion.

dodge - avoid (someone or something) by a sudden quick movement

duck - evade or avoid (an unwelcome duty or undertaking)

avoid - contrive not to meet (someone)

Solution 4:

If you are being somewhat secretive about your movements, you are being furtive.

Solution 5:

Inconspicuous; inconspicuously

To travel inconspicuously means to go unnoticed, to not be seen, to not be conspicuous, to not stand out or to not be prominent.

e.g.

The police waited outside for the suspect unaware that he inconspicuously escaped behind them.
